Notes on the cars:
- Osella PA9B/84  (Tony LaRosa): Martin Spetz observed the number 'Osella PA9B/84-126' on Trentini's Osella at Road Atlanta in 1984. As Mancini's car was also entered by Fiorano Sports Cars of Houston, as Trentini's had been, it is assumed to be the same car.
- Bobsy SR-6 (Peter Harholdt): Originally owned by Don Byer (Falls Church, VA), this Bobsy SR-6 was raced by driven in SCCA C Sport Racing (CSR) racing by Tom Luce, the "Racing Reverend", in 1977. The car was originally powered by a 1.3-litre Cosworth BDH, and is believed to have been the last SR-6 built. Its a second owner partly converted it to use a 1.6-litre VW Formula Super Vee engine, another available option for CSR, and this conversion was completed by Peter Harholdt (Falls Church, VA) when he acquired it. Harholdt raced it during 1985 and 1986, including in the Can-Am race at Summit Point, Harholdt's home track, in July 1986. He later sold the Bobsy to Oliver Kutnet (Charlottesville, VA). Subsequent history unknown.
- Rondel M1  (Randy Zimmer): Sold new to Chris Meek to run in British Atlantic and Libre racing with Tate of Leeds support; also used by Tom Pryce for three Atlantic races. Sold via Fred Opert to Mike Rand (Greenwich, CT) for Formula B in 1974 but damaged in a road accident. Sold still damaged, but with a new tub from Opert, to Ron Ignatowski; rebuilt and used in SCCA Formula C until 1980 when sold to Randy Zimmer as the basis for his Can Am car. Raced with a Volkswagen engine in 1982 and then with a Mazda rotary engine in 1983, 1984, 1985 and 1986. Entered for Jim Del Russo in the 1987 CAT championship. Retained by Zimmer as of 2011.
- March RX10-B [73B-17] (Seann Burgess): Originally raced by Bruce MacInnes (Sharon, CT) as part of a two-car team with Ron Cohn. After 1973, it was sold to Joe Ostrowski (Trenton, NJ) and used in SCCA club events until early 1982 when it was bought by Seann Burgess (Caledon, Ontario). Burgess won the CASC Ontario Formula Atlantic championship and the BARC Drivers Championship in 1982 as well as appearing in 'pro' events. After two more seasons of Atlantic, he converted the car to Can-Am specification at the end of 1985 and then fitted a McLaren M1B body and a Mazda 13B rotary engine for 1986. This "March RX10-B" was raced through the 1986 season. Burgess kept the March after it was retired from racing and is in the process of restoring it. By the beginning of 2012, he reckoned it was 90% complete.
- Royale S2000M  (Jeff Wright): Jeff Wright's Royale was entered as a RP37, the 1984 Sports 2000 model, but Wright's son has confirmed to Martin Krejci that it was a 1981 S2000M, chassis 17. Royale records, quoted in Paul Lawrence's book "Nowhere To Hide", show that this car was originally invoiced to Cooke Racing in the US. According to Doug Waters, the car used a standard Ford Pinto engine for its Can-Am and CAT appearances.
- March 85C  (Lou Sell): Lou Sell's #5 March 85C Can-Am car was identified at Willow Springs in 1987 by Martin Spetz as 85C-44 "ex-Michael Andretti Kraco".
- Watson (Buddy Lazier): For 1982, AJ Watson built a copy of a March 82C. The car was only used rarely but became one team's only remaining option when the 1981 car was rolled into a ball in Dick Simon's massive accident at Riverside late 1982. This is presumably the Watson-DFX that appeared rarely in 1983. Three years later the car reappeared as a single-seat Can-Am car entered by Texas American Race Teams.
- Photon JH2 [March 78B-15] (Jeremy Hill): Jeremy Hill's 1984-86 'Photon' was based on a March 78B Formula Atlantic car but fitted with a 2-litre Hart 420R engine, and a Frissbee-inspired body. A later advert for the car on Race-cars.com gives the car as March 78B/15, an ex-Brack car used for a season by Hill in Formula Atlantic before being converted to Can-Am spec.
