It's most definitely not the Riley GT2 Corvette
Anyway you can see it making the turn here this weekend, just after the black Corvette C5-R GT1/GTS

Would be great opportunity for more F1 fans to see these amazing cars... if they weren't binned to 8am starting slots when F1 sessions are in the afternoon...
