Son of the late Ronnie, Jeff has been a long time endurance driver who had a few IRL attempts in 2005 and 2006. He also then ran a team, and raced in endurance, but recently has been concentrating on his role as a Camaro ambassador, test driver and coach, although he did the very infrequent race in them too or in SCCA events. He also is a race instructor and runs an auto racing supply shop in his base in Lake Havasu City. As well as this, a current focus is on his motorsport management firm. Before racing, Jeff was an accomplished surfer, competing all over the World. Bucknum's son, Spencer, has also raced single-seaters.
