Notes on the cars:
- March 732 [4-2] (Vittorio Brambilla): Beta Racing Team for Vittorio Brambilla 1973 and used as his main car all season. Crashed at Monza in June and rebuilt on a new monocoque. Crashed again in practice at Vallalunga in October and may have been written off, leaving Vittorio to drive brother Tino's 732/5 at the last race. This car appears to have been repaired on a new monocoque and retained by the team as a spare in 1974. It would be the car raced by Diulio Truffo at Mugello and Alberto Colombo at Vallelunga. It remained with the Brambillas until 1977, when it passed to sponsor Daniele Ciceri of Beta Tools, and was placed on display at the Beta factory. It 1988, it passed to the Autorevival Italia Association, and was displayed in the Museum Autodromo Monza until 2000, when it was acquired by Guido Romani (Milan). It was sold to Hall and Hall (Bourne, Lincolnshire) in 2019 when it was found to be in remarkably original condition. Sold to Graham Adelman in 2019.
- March 732 [6-2] (Jean-Pierre Jarier): STP March Engineering works car for Jean-Pierre Jarier, winning the two opening rounds at Mallory Park and Hockenheim, but then crashed at the third race at Thruxton in April. Rebuilt on a new tub and raced by Jacques Coulon at Nivelles-Baulers in June. Thereafter Jarier's regular car, winning at Rouen, Mantorp Park, Karlskoga, Enna-Pergusa and Estoril. This may be the March 732 that was later exhibited in the BMW Museum, which is exhibited wearing the #23 that Jarier used at Rouen. A visit by Motor Sport magazine in early 1975 (Motor Sport March 1975 p245) mentioned a 732 being on display, and the car has been spotted on subsequent occasions.
- March 732  (Jean-Pierre Beltoise): STP March Engineering works car for Jean-Pierre Beltoise at Hockenheim and later by Jean-Pierre Jarier at two races. Probably the car used by Jacques Coulon at Hockenheim, by Beltoise at Albi and by Stuck at Estoril. To Brian Lewis Racing for 1974 and updated to 742 spec for Andy Sutcliffe as '742-10b', then run for hire drivers later in the year. To Roger Heavens for Antônio Castro Prado for F2 in the latter part of 1975, then sold via Hervé Le Guellec to Jimmy Mieusset as a backup car for French hillclimbing at the start of the 1976 season. Also used by Roger Rivoire in May 1976, and then sold to Jean-Pierre Simon in June 1976. Retained by Simon for 1977, still with its BMW engine. Unknown in 1978, when it could have been the 742-BMW of, for example, Robert Despratx in southwest France. Then to Maurice Crozier and raced in 1979 and 1980 with a 1600cc Ford engine. Advertised by Crozier with or without its 1600cc Cosworth FVA engine in November 1980. It was next seen with Michel Goutarel, who raced it in courses de côte in the Lyon area in 1981 and 1982. Goutarel appears to have kept this car for some time, as he is noted as the winner of the Course de côte régionale de Vals-prés-Le-Puy in September 1986.
- March 732  (Jacques Coulon): Ecurie Filipinetti for Jacques Coulon with Antar sponsorship, completed on the Saturday morning of the opening Mallory race, but did not start. Transferred to Brian Lewis Racing after Georges Filipinetti's death in May. To Gérard Pillon (Geneva, Switzerland) 1974 and used in Swiss national events. In 1977, Pillon loaned it to his fellow Genevois Laurent Ferrier for the European F2 races at Hockenheim and Vallelunga, but Ferrier could not qualify the old car for either race. Pillon then appeared at three F2 events in 1978 in a March-BMW variously described as a 762 or a 782, and it is possible that this was the old 732 again. The 732 was next seen in 1979, driven by Ami Guichard, son of the Automobile Year editor of the same name, in French hillclimbs. After driving Pillon's new 782 in 1978, Guichard returned to the 732 and was still racing the car in Swiss championship events in 1988, when it was described as being largely original. The car remained with Pillon thereafter, and was still in Switzerland in 2015.
- Elf 2 (Alpine) A367  (Jean-Pierre Jabouille): New in mid-1973, for Elf Coombs Racing team leader Jean-Pierre Jabouille to drive in F2. Raced with Cosworth BDG and Hart alloy-block BDA engines. Retained for 1974, fitted with a Schnitzer BMW engine and assigned to Michel Leclère for that season, but probably the car raced by Alain Cudini at Hockenheim. Two effectively new cars were built for 1975 consuming two of A367s, this car becoming chassis 7501.
- Surtees TS15  (Jochen Mass): A new car for Jochen Mass as a Team Surtees FINA entry at Mantorp Park in July, replacing chassis TS15/03 which had been badly damaged at Monza. Then raced by Mike Hailwood at Karlskoga, by Mass at Enna, by Pace at Salzburgring, then by Mass again at Albi and Vallelunga. In that final race, Mass was running second in the final stages of Heat 1 when he understeered into one corner, slid across the grass and hit the Armco, wiping the suspension off one side of the car and "putting a huge dent in the monocoque".
- Motul M1  (Tim Schenken): The car raced by Tim Schenken for Motul Rondel in F2 in 1973, and believed to be the same car all season. Then sold via Fred Opert to Stutz Plaisted Racing, and raced for the team by Peter Symonds (Salem, MA). Symonds car in SCCA Formula B during 1974 was entered as a Cheetah, but when he appeared for the SCCA Formula B race that supported the US GP at Watkins Glen in October 1974, his car was given as a Rondel M1. The car was apparently owned by Plaisted's father, John Floyd Plaisted, and it was still in his possession when he died in February 1979. Many of his cars were sold at auction in December 1979, and the Rondel was bought by Bob Connearney (Andover, MA) and retained by him. It still has the Ford twin cam engine it would have used in Formula B in 1974. Robert Connearney passed away in June 2020, and his collection of cars was offered for sale by Clarke Taylor at Historic Motor Sports (Candia, NH). The unrestored and heavily corroded Rondel was on display at a a VSCCA event at Lime Rock in July 2020, still in its Stutz Plaisted Racing livery, and still wearing its original 203 chassis plate.
- GRD 273 (Bertil Roos): The works Formula 2 entry intended for Dave Walker to drive in 1973, entered by "DART racing with GRD", a tie-up between GRD and Scottish industrialist Dennis Dobbie. Walker was injured, and the car was due to be raced at Malory Park, the opening F1 race, by Tom Walkinshaw, but he wrecked it in a test at Snetterton a few days before the race. The car was repaired later in the season and hired by Fred Opert for his driver Bertil Roos to race at Mantorp Park in July, and at three later races at Karlskoga, Albi and Estoril. Subsequent history unknown, but a "little used", "ex-Bertil Roos" GRD 273 rolling chassis was advertised from Northampton in March 1981 and this is the only GRD Roos raced.
- March 732  (Motoharu Kurosawa): For Colin Vandervell, run by Brian Lewis Racing. Vandervell became disillusioned with F2 and the car was rented out to other drivers, notably Motoharu Kurosawa. Unknown after 1973 but there are no unexplained 732s in Japan to suggest Kurosawa took it home. This could be the unexplained 732 of Jean Lapierre in French hillclimbs in 1974.
- Chevron B25 [25-73-08] (John Watson): New to George Silverwood and entered by his Central Garage (Mirfield) Ltd for John Lepp in British Formula Atlantic in 1973. Also used by Lepp in the first European F2 round at Mallory Park, with the 1.6 BDA still in it. Lepp's sports car racing took priority from July and the B25 was sold to Patsy McGarrity (Belfast, Northern Ireland) for Formula Ireland racing. Loaned by him to Chevron cars for John Watson to use in the F2 race at Albi. Converted back to Formula Atlantic for McGarrity to race in the 1974 Irish season, winning eight races and the All-Ireland championship. Sold on to Pat Woods (Newcastle, County Wicklow, Ireland) for 1975, and retained for two further seasons. Last seen when Woods crashed heavily in practice at Phoenix Park in September 1977, when the car was described as wrecked. Woods' daughter later told James Murray that he sold the wreckage of the B25 to Bobby Howlings. Subsequent history unknown.
- Motul M1  (Jean-Pierre Jaussaud): The car raced by Jean-Pierre Jaussaud for Motul Rondel in F2 in 1973, and believed to be the same car all season. Also raced by Tim Schenken at Karlskoga in August. Subsequent history unknown, but the car later raced by Iain McLaren was described as "ex-Jaussaud".
- Brabham BT40  (John Wingfield): New to John Wingfield and raced in both F2 and Formula Atlantic in 1973, entered by Marshall Wingfield Limited. Raced by Ray Mallock in Formula Atlantic 1974, entered by The Chequered Flag, and retained for one early-season race in 1975, after Mallock wrecked his new March 742 at Thruxton. Then entered by Marshall Wingfield Ltd for South African Len Booysen to drive in a few Formula Atlantic races in June and July 1975, by which time it had acquired what looked like a March 73B nose, before Wingfield himself raced it once more at Silverstone in August. Subsequent history unknown.
- Surtees TS15  (José Dolhem): A brand new car prepared for Mike Hailwood to drive at Thruxton in April 1973, the third round of the 1973 F2 series, but after Hailwood was disqualified from the heart, the new car was driven by teammate Jochen Mass in the final. Then driven by Derek Bell at the Nürburgring as Hailwood was at the Spanish Grand Prix. Driven by Willy Braillard as a works entry at Nivelles-Baulers, then for Bell at Hockenheim, then for José Dolhem at Rouen where he crashed in practice and did not start, and then for Bell again at Monza a week later. Hailwood then drove this car at Enna in August, then Dolhem at Albi, and it was presumably the unused spare at Vallelunga. This car was not seen again, so it could be one of the cars that went to Japan, or the car that was destroyed over the winter in a transporter fire.
- Chevron B25 [25-73-07] (Peter Gethin): Chassis number given by Motoring News (MN) 12 Apr 1973 p11 for the works car for Peter Gethin in the 1973 European F2 championship round at Hockenheim. Used by Birrell at Pau in Gethin's absence, after Birrell had damaged chassis 9 at the Eifelrennen, with the rear end of that car grafted on to the Gethin tub. Gethin returns to the car at Nivelles, 10 June (MN 14 June 1973) reporting it was the first time he had used it since Thruxton. Probably the car entered for Gagliardi but DNA at Monza Lotteria. Used by Lepp at Estoril in October 1973, with an FVC engine fitted. Sold to Reg Phillips (Tewkesbury, Gloucestershire) for hill climbs in 1974 and fitted with a 2-litre BDA engine. It was retained by Phillips for 1975, when it was called a B25/B27, and for 1976, when the engine was enlarged to 2150cc. This is likely to be the 2.2-litre B25/B27 used in hill climbs by John Stuart (Bridgnorth, Shropshire) in 1977 and 1978. It was last seen in Stuart's hands at Doune in September 1978 when Stuart used it to uproot a tree stump. Sold, still damaged, to Jeremy Bouckley (Sutton Coldfield, West Midlands) who advertised it in early 1979 (together with a complete F/Atlantic B25), with the intention of breaking it for use in Super Saloons. Bouckley recalls that the car was broken up, but has no note of who acquired parts of it.
- Motul M1  (Tom Pryce): New for Tom Pryce at Mantorp Park F2 in July 1973, and at three more F2 races that season. Believed to be the car raced by Chris Meek in a formule libre race at Croft in October 1973. Sold via Fred Opert to Roger Seacrist (Chicago, IL) for SCCA Formula B and Canadian Formula Atlantic in 1974. Retained for SCCA Nationals in 1975, when he finished third in a strong field at Blackhawk Farms in August and scored five points in Central Division FB. Advertised in Autoweek in March 1976 from an address in central Chicago, quoting the chassis number. In 2011, this car was reported to be "currently resting in rural Illinois".
- March 732  (Bill Gubelmann): New to Bill Gubelmann (Oyster Bay, NY) for F2 in 1973 and retained for 1974 when run by Brian Lewis Racing. Clay Regazzoni was due to drive the car at Vallelunga in October, but did not arrive, so a deal was done for Gabrielle Serblin to drive after he damaged his usual 742 in practice. Not seen in 1975, when the intention had been to sell the car to Stuart Chubb Racing, but Gubelmann returned for the 1976 Shellsport G8 series with the car updated to 752 specification, fitted with a Hart BDG, and run by Bob Gerard. Gubelmann also appeared in a handful of F2 races in 1976, but after failing to qualify for the Rouen race, quickly moved to Mallory Park in time to qualify for the Shellsport race. He was involved in a nasty accident in the race when he clipped the rear of Mike Wilds' F1 Shadow, rode up over its back wheel and hit the bank at the Esses very hard. He was taken to hospital with head injuries. The March is believed to have been destroyed.
- Motul M1  (Bob Wollek): The car raced by Bob Wolleck for Motul Rondel in F2 in 1973, and believed to be the same car all season. Like most of the team's cars, this went to Fred Opert for 1974 to be converted for use in SCCA Formula B and Canadian Formula Atlantic. Assuming Wolleck used the same car all season, this would then be "ex-Wolleck" car that Seb Barone (Portland, CT/Middletown, CT/Dilliner, PA) remembers buying for 1974. After a season in the Canadian Formula Atlantic series, Barone traded it back to Opert for his 1975 Chevron B29. According to Cy Morland, who owned chassis 207 from 1998 to 2008, the car was owned after Barone by John Stowe in New England for an extended period, so would be the Rondel raced by Stowe in New England Region SCCA Regionals in 1976. Morland had the tub completely rebuilt by Marc Bahner, and then sold the car back to England. Subsequent history unknown.
- Motul M1  (Henri Pescarolo): The car raced by Henri Pescarolo for Motul Rondel in F2 in 1973, and believed to be the same car all season. Also raced by Tim Schenken at Pau, Kinnekulle Ring and Rouen. This car was fitted with a Schnitzer BMW engine for the last two races of the season. Then believed to have been sold via Fred Opert to the US so this may be the car wearing Pescarolo bodywork that was sold to Alistair Justason (Toronto, Ontario) in 1974, then Bob Beyea in 1975. Chassis 206 was later bought from Opert by Randy Zimmer as a source of spares for his Can Am car. Still with Zimmer in 2010, but by July 2011, it had been sold to Richard Parkin and Martin Walker in the UK. From them, it later went to Martin Donn, still unrestored, and then to Steve Worrad in January 2019.
- GRD 273 (Hiroshi Kazato): A "brand new" GRD 273 built in time for the Mantorp Park race in August 1973 and fitted with a Schnitzer BMW engine for Hiroshi Kazato, entered by GRS International. The car was then an unused spare at Karlskoga as no engine was available, after which Kazato drove the car at Enna and Albi. Subsequent history unknown but two "ex-Kazato" GRD 273s are known later, one run by Alan Clennell in hillclimbs and one on display in Japan. One of these will be chassis 054, but the other is likely to be this ex-BMW car.
- Brabham BT40  (Wilson Fittipaldi): Run by Motor Racing Developments as a works car in Formula 2 in 1973, fitted with a 2-litre David Wood BDA raced at first by John Watson at Mallory Park in March, but after he was injured in a F1 Brabham BT42 at the Race of Champions a week later, the BT40 was taken over by Wilson Fittipaldi. A Schnitzer BMW engine was tried in the car at Rouen in June, but the car had its Wood engine again when Fittipaldi won a non championship race at Misano in July. Sold to Eugenio Baturone for Spanish hilllcimbs in 1974, still with its 2-litre Wood BDA engine. Retained by Baturone for three more seasons, then sold to José Canela Ballesteros, who raced it in hillclimbs in 1979. Acquired by an Italian lawyer who owned it for many years. Bought by Giulio Vezzoli (Brescia, Italy) in December 2018.
- GRD 273 [076-F2] (Brendan McInerney): Raced by Tetsu Ikuzawa in F2 in 1973, entered by GRD's racing offshoot GRS International. When Ikuzawa had returned to Japan in August, the car was used briefly in practice by Hiroshi Kazato in practice at Enna and was then taken over by GRS teammate Brendan McInerney whose own car had been wrecked at Karlskoga. Revamped in DART colours for Noritake Takahara to race at Estoril at the end of the season. Subsequent history unknown.
- Elf 2 (Alpine) A367  (Michel Leclère): Entered as an "ELF 2", but built by Alpine and designated the A367. Chassis 3670 was built for the 1972 F2 season, when it was raced by Patrick Depailler and Jean-Pierre Jabouille. This is apparently the same car that was updated for 1973 and became Depailler's regular car that season. Substantially redesigned by Andre de Cortanze for 1974, and fitted with a Schnitzer BMW as a fourth team car for Alain Serpaggi and others to race. According to reports, this car started to be converted to 1975 specification, but was unfinished. In 1999, this car was reported to be owned by Thierry Gay (Lyons), and Gerard Gamand reported on Autodiva that the car had been reconstructed using a new chassis fabricated by Gilles and Vincent Duqueine. In 2015, Fred Marquet's HTT Motorsport was restoring this car to its 1974 Serpaggi specification. It was first seen at Albi in June 2016.
- March 732  (Roland Salomon): To Roland Salomon for Swiss championship events from June onwards, replacing a GRD 272, and also some F2 races that season. After winning the Swiss title, the car was damaged in a hillclimb near the end of the season and rebuilt on a new tub in time for the Estoril F2 race. Salomon continued with the car in 1974 but focused on national events. Sold to Beat Blatter 1975 for Swiss Championship events.
- Surtees TS10  (Silvio Moser): A new car built up for the Matchbox Team Surtees F2 team in mid-1972, and first raced by Dieter Quester at the Österreichring in early July. Raced later in the season by Carlos Pace, John Surtees and Mike Hailwood. It is almost certainly the car raced by Lian Duarté in the F2 Torneio do Brasil. Sold to Silvio Moser for 1973, repainted in Marlboro livery, and used regularly through the 1973 F2 season. Raced by Alberto Colombo at Vallelunga at the end of the season. According to Beat Schenker, Moser's mechanic, the Surtees was sold to a Mr Herber, from Ticino, who planned to use it in the Swiss national championship. Beat recalls that he crashed on his second or third outing, and believes the car may have been a total loss.
- GRD 273 [054-F2] (Hiroshi Kazato): New to Hiroshi Kazato, and run for him in 1973 F2 events by GRS International. Kazato used Racing Services alloy Ford BDA engines at first, then moved to Cosworth BDG, and then had a new car built to take a Schnitzer BMW, retained chassis 054 as a spare. Chassis 054 is thought to have been sold to Chris Oates for 1974, and the "ex-Kazato" car that he ran in Formula Atlantic for Richard Morgan and then Frank Sytner, but this may have been an older car. Chassis 054 reappeared in 1976 when it was run in libre racing by Alan Clennell, described as a B73 and using Swindon BDA engines. Retained by Clennell for sprints and hillclimbs in 1977 and 1978. Advertised by Clennell (Southam) as an ex-works 273 in November 1978. Subsequent history unknown.
