I saw that car at the Silverstone classic in July, a blue GT40, number 40 I think. I got talking to the guy who was with the car in the garage area, nice chap. Don't know about the Donnington event, but at the Silverstone Classic he raced it. It finished 34th out of 35, did 34 laps, finished 7 laps behind the leader and his best lap was a 2.15.262
Having watched the race he did very well, those T70s were in a class of there own.
