I would question the engine stamp. Is the seller claiming the paint is original?
If you look closely at the pics, you can tell the car has had one repaint, maybe british green, but still one repaint. Maybe he doesnt know the history of the car, but I would ask him, and see if he says its been repainted. IF not, then he doesnt have knowledge of factory camaros. The guy may be telling what he knows, but if he doesnt know something, how would he know to tell you that the previous owner of the car removed the rear bumper guards???
Also, the shifter and know are wrong. If you are interested in buying the car, email me and I will tell you how to tell if the tach is correct? As for the special paint code, it doesnt apply to stripes; either blk,wht or none. The engine code stamp looks more real than not, so its a MO block, but the VIn stamp story I dont buy, cause there are two flaws in it, one digit and the N is missing. It looks like someone tried stamping the vin in one digit at a time. It is a nice clean undercarriage.
