"Mostly original Z/28" he states a "correct 302" in the beginning of the ad, and then later on goes on to describe a X-33 car, when it is clear this is a X-77 car. To many questions I think, surrounding this car, to take a chance everything is ok. It seems you have to thoroughly research and investigate these cars to being with, and then you run across a car like this that raises a lot of suspicion to begin with. This car could be legit, it may take a Camaro expert to look at it, or the protecto plate to prove that it is what it is advertised as. Just like to make sure people get what they are paying for, is all.
