Many thanks for answering.
I wish it was one of the Tauber cars, but sadly its not. That green is much darker than the colour on my car.
If you watch the second video at about 26 seconds in the anouncer says something like "three minutes later, the next group starts ....<something I cant catch> ...group N cars" (sorry my German is really rusty), and then what I think is my car crosses the line.
Any ideas where I can get the entry list for the 1991 race?
