There was a Group C/GTP Sports Car race at the SeeRed meeting at Donington Park in September 2007 and here is one of the cars which took part in that race.
It's a 1990 Jaguar XJR-12, driven in the race by Justin Law and here seen in the pit garage. The programme of the event said this about the car:
'Well-known historic hotshot Justin Law will be racing the Jaguar XJR-12 this weekend. Part of the established father-and-son team running Don Law Racing, Justin has burned up the tracks in his inimitably flamboyant and hard-charging style all over the world as he has progressed from a Jaguar Mk2 to Group C. He has also driven a Lister Storm to 2nd at the Spa 24 Hours (2003). The XJR-12 he will be piloting this weekend ran at Le Mans in 1990 driven by Ferte/Jones/Perez-Sala, but did not finish. When it retired from the tracks in 1993 it spent a decade in the TWR museum before being revived.'
Tom Walkinshaw Racing entered four of the XJR-12 cars in the 1990 Le Mans race, two of them failed to finish but the other two finished in first and second places.
Here's Justin Law at the Old Hairpin during a practice session......
