1987 Buick Grand National - Well maintained hardtop with upgrades


After enjoying my Buick for the last few years, and meeting (or re-meeting) a bunch of great folks along the way, it's time to sell my GN. With two little ones at home and a new (time-consuming) job, I don't have enough opportunity to take it out and have fun.

Asking $25,000. Lots of details below, pics coming.

Car drives beautifully and has a lot left in her. Hate to see it go, but it's just sitting in my garage right now. Still have the original turbo, intercooler, and powermaster unit too.


Pictures here. If there's anything in particular you'd like to see, please let me know.



Thanks. I love this community and met lots of good people here. I'd like to be honest and transparent, go fast with class.

I want the buyer to know everything they can about the car before they come see it; saves everyone time if there are no surprises.
