Cool cars...I always liked these too!.
Vehicle being discussed is Vin # 1G1AP87L6BN116459
Love how the past owner and VP of his company doesn't even have enough sense to notice how to spell Yenko correctly...sharp fella??.
As delivered Yenko mods wouldn't be included, but to back up some info shown, don't forget the possibility of GM Canada docs being available...remember the chances are good for any '77 & up Camaro, Canadian & US cars!.
