I photographed this car in the main paddock at the Coys International Historic Festival meeting at Silverstone in July 2000.
It's apparently a Lancia Stratos, although there are plenty of replicas around, notably the ListerBell and Hawk, and the 'F' on the number plate indicates a car that was first registered in 1988/89 whereas the Stratos was only produced between 1973 and 1978. On the other hand an older foreign registered Stratos could have been imported into the UK at a later date and been given an 'F' registration. The names shown at the top of the door are Björn Waldegård and Hans Thorszelius and underneath that and above the number 11 it says 'Rallye Monte-Carlo'. Those two drivers finished second in the Monte Carlo Rally in 1976 in a Lancia Stratos, but the car was number 6 and the livery was different. They were, however, the winning team in the 1975 San Remo Rally in a Lancia Stratos number 11 and with that livery. Björn Waldegård was present at this Silverstone meeting and drove a Lancia Stratos in the Historic Rally Sprint competition, so it could be that car, although the Rally Sprint paddock was on the far side of the circuit alongside the Hangar Straight.
