I had a 73 Gran Sedan back in the late 80's. It was one of the best Furys I ever owned. Unfortunately, it was my daily driver and the 400 drank gas like it was free! I was spoiled by the MPGs of the 318s I had in most of my Furys. lol
When I worked at a Pontiac store back in 81, a Grand Prix came in with severe roof damage. The Pontiac rep had to witness the car get crushed. I also remember Chevrolet donated a new Monte Carlo to my High School that was a flood car. The VIN was removed.
