Most performance bang for buck is always gonna be a used car.
Maybe you're right. Any time I have met a GT500 owner or a fancy vette owner, they have not even explored the upper echelons of their vehicles' performance. Cars and coffee commute and then a quick babying in the garage.
I know some of the 911/Cayman guys are looking at the new mid engine Vette for sure, but that makes more sense as the Germans are stupid expensive for what they use it for- tracking and autocross.
Some people aren’t looking for used. But yes, I’d agree with you there.
