For the amount one (I fucking hope...) dealer is charging for a C7, you can get a used Gallardo. I browse DuPont a lot and see these for just a hair under $100k. So, would you take that deal?
I wouldn't. I say that as someone who grew up riding in the back of F-bodies, who's mother's car was a third gen formula 350, who spent much of his childhood making paper V8 models. I want an LS1 about as bad as you want your cock inside Christina Hendricks. But no. The C7 is not as good as a semi-rare italian sports car.
That's not GMs fault though. They're not the ones asking $100k for their very good, vastly improved sports car. This one moronic dealer is. This is why we can't have nice things, people.
