1986 Buick Grand National Coupe 3.8 Liter SFI Turbo V6

I’m selling my 1986 Buick Grand National. The car is in excellent condition.
Mileage:
51,835 (Original Miles)
The original owner did a partial GNX Clone conversion back in the late 80s. Once I got the car, I decided to take what he had done and go a bit further leaning toward a pro-touring GN with X influence. The car has had no accidents. In January of 2009 it went in for a paint job. All doors, hood, trunk, glass, etc. were removed then re-installed after paint. All new glass was installed along with new door gaskets, window gaskets, carpet and other items listed below.
Exterior:
7.5-8/10. I am very picky and can find imperfections but this car was built to be a driver. It’s not “garage queen” perfect but it is very much show worthy and looks fantastic.
Interior:
7.5-8/10. Again, with me being picky, I can find things that aren’t perfect. That said, the interior is in really nice condition. The seats, headliner, visors, dash, console and some other various trim pieces are original. I have also added some new custom pieces as well as the addition of new upper & lower door panels and carpet. There is also a nice trunk kit installed.
Wheels/Tires/Brakes:
7.5-8/10. The wheels are Boze Forged "Mesh" Wheels - 18x8 Front, 18x10 Rear wrapped in Nitto NT555s - 245/40/ZR18 Front, 285/35/ZR18 Rear. The tires are older but still have a decent amount of tread.
Engine/Suspension:
7.5-8/10. The factory 3.8L SFI Turbo V6 is still in the car. It was freshened up back in 2011. The typical bolt-ons are in place and are listed below. Methanol injection is on the car and under 28 pounds of boost, the car should be in the 550 HP range although I never have put it on a dyno (nor have I raced it on a track).
The List Of Mods:
As I stated earlier, I will try to cover the list entirely but with everything I have done over the years, I may miss something. This list should sufficiently cover the very large majority, though.
