Yes, they do keep getting better and better.
Funny thing about the 74 Corvette winning GT Pro was that it was the slower of the two Corvettes, and came from a lap down with just over 2 hours felt to win. The 73 Corvette was actually DOMINATING GT Pro for most of the race til it was taken out by a Porsche that it was in the process of putting another lap down.
Woulda' been nice to see a Corvette 1-2 finish in GT Pro.
We'll take First Place by itself, though.
