Listing this for a friend of mine. He is relocating out of state and doesn’t want to take the car with him.

1987 Buick Grand National hard top, 104k miles on the body, less than 10,000 on the motor. Car runs very strong and is tight. Comparing it to my mid 10-sec car I would guess this will run mid 11’s easily.

Body is very straight and there is no visible rust. This car spent its life in Virginia until he purchased it in 2013. Under the car is very clean. Carfax came up clean but AutoCheck reported a “minor accident” in 8/91.

Paint is a 10 footer but looks presentable and cleans up nice. Fillers are still in good shape. All badges are present and in nice shape.

A/C was converted to 134 and blows cold.
