It's not very often you see a track-focused 1969 Chevrolet Camaro ZL1 up for auction because only 69 were made. It also happens to be one of the most desirable Camaros ever built. At the time, Chevrolet didn't offer the car with an engine larger than 400 cubic inches due to safety fears. However, Illinois dealer Gibb Chevrolet used the automaker's Central Office Production Orders department to order Camaros equipped with 427 cubic inch V8 engines developed for Cam-Am racing.

The unit had a claimed 435-hp rating, but in reality, it pumped out over 500 hp. As a result, the Camaro ZL1 was barely road legal and was often seen tearing up the drag strip. Essentially, this was GM's first true rival to the mighty Mustang.
