PRICE: $23,900 OBO

Hey guys,

I am selling my pristine condition 1987 Buick Grand National. I have owned this car for four years (bought it on this very forum from an awesome gentleman out of South Carolina) and in that time have put only about 5000 miles on it, bringing the total original miles to just over 42000.

It's always garaged, always covered, and in perfect condition. This car gets a ton of attention; every time I take it out it gets stares, thumbs up, and starts conversations all over town with people of all ages. If you want to be left alone, this is not the car for you.

This car looks all original, but the engine and transmission are built for performance. The entire power train was fully built by Wildcat Performance Engines in Adel, GA at 36000 miles with all top of the line parts (see all specs below.) This car is unbelievably fast and sounds incredible. The paint is original and in great condition, and the interior is in perfect, showroom condition.

This car has been treated like a collector from day one. It comes with all the stock parts, along with a binder full of all receipts and records, plus the original window sticker and build sheet. This car was once owned by Dennis Kirban (if you're on this forum, you know who he is.) It also comes with a total of six GNX wheels, four with Eagle F1 tires and two with Mickey Thompson drag radials.

During the entire time I've owned the car the only person who has turned a wrench on it is "Turbo Lou" Czarnota, a true legend in the turbo Buick world on the west coast, and he would be glad to vouch for the condition of the car. There is nothing more that you could want in a Grand National.

If you have been looking for a true collector grade Buick Grand National that has the looks of a showroom condition car - but with the performance these cars are meant to have - you've found it. Many more pictures, video on request.

A suggestion... Take the pics w/ a flash fill and stay out of bright sunlite. There's little to zip detail, due to shadows..It would help a lot w/ your ad...
Still for sale guys. This is a 500 HP build done with no expenses spared only 6000 miles ago, I have receipts and records for absolutely everything and the car is in almost flawless condition. Not a lot of cars like this out there!
Does tranny have a transbrake and where is the car??
