Description:

This relatively rare Chevron F2 car was driven competitively by David Purley for John Harper in the European F2 season. Now fitted with a unburstable Cosworth YBM in place of the unobtainable BMW it is ready for Formula 70 Group I events. The car has been completely restored and is nicely fitted out and presented.


History

The 1974 F2 season saw wealthy Hong Kong businessman John Harper order March 742/BMWs for his drivers David Purley and an out-of-retirement Dieter Questor. When the works Marches appeared with a specification totally different than the customer cars and were clearly superior Harper switched to Chevrons in retaliation and scored some good results. This car is the David Purley car and took a 2nd at Pau and Rouen against the supposedly unbeatable works Marches of Stuck and Depailler.Engine
