It's hard to beat the sports appeal value of a T-Top Z28 at seven-and-a-half grand. It's an extremely fun and powerful ride that has a high cool factor without everybody thinking that your parents gifted you a brand new sports coupe. Although it won't be easy on the pocketbook regarding gas and insurance, the smile you'll notice on your face every time you step into your sweet American ride makes it worth it.
