I'll be watching. Last year I was able to attend (cross that off my bucket list!) and the Corvette was BY FAR the most fun car(s) on the track for sound (although the AMs were probably second). They rumbled like an old WWII airplane going down a runway. It shook the stands. At the end of the race, when the cars were doing one last wave to the stands before heading to the pits, the Vettes all did burnouts for about 100'. Just fantastic!
In the P1 class, I root for Audi too. Although, I'm gonna keep an eye on that new Nissan. It looks bonkers.
