87 GN for Sale


Death by boost
$19,500 OBO I have a very nice fully built 1987 Buick Grand National with only 85,000 original chassis miles and about 2-3000 on the new engine tranny setup. I have owned this vehicle since January 2006 and when I bought it, it was in pretty rough condition. The engine was pretty beat up and the tranny was in bad shape as well as the rear end and exterior. Over the last 4.5 years I have put about $27,000 into it in parts, machine work and labor only NOT including the original buying cost of the vehicle. I know this is a lot of money to ask for a car in these hard times but once you see the car you will understand why I am asking so much (the price is slightly negotiable). I know this car inside and out and can walk you through the entire vehicle and all the upgrades. I have receipts to prove everything I have put into the tranny and engine and they come with the car (all machine work was done at U.S. Automotive Performance by Jeff, if you know them you also know how good they are). I will list all of the upgrades that I can think of following this posting and if you have any questions please don't hesitate to ask. I am currently on my honeymoon and will be back in town by Monday the 26th, and I will post pictures at this time. The car does leak a small amount of oil due to the racing girdle that is on the car, it is very rare to find a car with a girdle that doesnt leak a small amount of oil . I may be interested in trades but would rather have the cash to pay off bills. I am NOT interested in any MOPAR, Chrysler or Ford products however. Let me know if you have any questions. SERIOUS INQUIRES ONLY PLEASE.
