Not a supercar, but a unique 77 Vette for sale
 

My boss has a 1977 Corvette he's trying to sell. He's the original owner, has all the paperwork including the order form, window sticker, shipping order, brochures, under 26K miles. The car is Silver metallic blue with white leather seats and door panels with blue carpet and dash(special ordered combination). It's a 4 speed, L82, loaded with options including aluminum wheels. He even has the factory recalled and replaced white letter tires still on it. He also has a set of the smoked Saratoga T-tops to go with the car. I have bunch of pictures if anyone is interested. $17K, email me or send me a PM and I can get you in contact with him.
