 In their formative years, McLaren built Formula Two, hillclimbing, Formula 5000 and sports racing cars that were sold to customers.Lacking the capacity to build the desired numbers, Trojan was subcontracted to construct some of them.In Can-Am, Trojan built customer versions of the M6 and M8 cars and ex-works cars were sold to privateers when new models arrived; half of the field was McLarens at some races.
