Also, re the OldRacePhotos image, if you look at the people in the background, you'll see several of them wearing short sleeve tops. The ATCC Symmons race was run in the wet, and photos of the race show the spectators to be well wrapped up with many carrying umbrellas, which makes me think the OldRacePhotos image was possibly taken not on race day. So if the race was on Sunday, perhaps the Camaro expired in practice in Saturday?
