Chassis SL71/46 is a 1966 Lola T70 Mark II GT Coupe, originally built at the Slough factory and delivered as an open-top Spider to John Mecom of Texas. Raced by Jerry Grant during the 1967 Can-Am and USRRC seasons, the car subsequently received Mark III closed bodywork and larger brakes. After passing through several owners it spent a decade campaigned by PRD Racing at Sears Point. The engine was rebuilt to 385ci producing 650bhp, and the car has been active in California historic racing into the 2000s.

Each chassis record is compiled from public auction archives and links to its source material. Ownership, competition and maintenance entries are extracted from those catalogue listings by an LLM, which can make mistakes — please contact us with any corrections.
