The Chevy Corvette is probably one of the most versatile cars out there. One can buy an early 2000's Corvette have 350-400 horsepower under the hood from stock and a good suspension. The aftermarket is huge and relatively cheap plus there are a ton of specialty shops out there to pick from. The only aftermarket that even matches what the Corvette has is the Mustang but performance wise the Corvette is a better car mostly if you're talking the past 15 years or so.
If some one gave me $30 grand and told me to ready a car for some kind of car shootout the Corvette would be my pick.
