Seen here is what is likely the Camaro SS!! It was spotted by one of our members with his cellphone in Mesa, AZ, outside the GM proving grounds. It is being tested concurrently with other similarly configured Camaros in the GM proving grounds. From what we can see, the car's distinguishing body work includes the black hood stripe and hockey stripes running down the sides of the car.
We've been told that it sounded like "a demon"!
And had a whistling sound at idle
