Chevrolet Corvette ZR-1

At first glance, the ZR-1 looks like any other C4-generation Corvette. But look a little closer, and you'll begin to see some changes. The body is wider, and the tires are too. Under the hood sits a DOHC V-8 designed by Lotus making 375 horsepower. It could get to 0-60 mph in under five seconds, which was damn impressive for the time. Here's one you can own right now for under $30,000.
