9. 1986 Corvette “Copper Metallic”
The 1986 model of the Corvette was often panned by critics for its lackluster 305 V8 engine, but there was a rare variation of the vehicle. The “copper metallic” version of the 1986 Corvette was so rare that only four were made. It was a test color for GM and four owners had opted for the model. This particular color is a difficult one for GM to get on the Corvettes of this era and there were a lot of quality issues. The bubble light on the back of the car was also unique to this model year.

The next model year was better for copper metallic as there were 87 examples that hit the market. But the 1986 model was the rarest, and if you can get a hold of one you’ll have one of the nicest C4 models around. This car was not the prettiest Corvette around by any means, but the copper metallic was certainly a welcome addition.
