Clean 1986 Buick Grand National - Up for sale 1986 Grand National GNX Clone. It is a excellent running and fast car. I just replaced the front filler panels and the front fiberglass bumper. I never race the car. If you are interested to buy text (302) 408-2543 me your email and I will send you more info and pics about it. It has only been driven to local car shows and parades. Have nice day!!
