Buick's Grand National was in a class of its own. This was one of the fastest American production cars of its time. This is a true 1987 Buick Grand National with GNX trim added throughout. This is not one of the original 547 GNX Grand Nationals. This car has just had the GNX aesthetics added for the look. This car can't be told from an original GNX from the exterior or interior. This '87 GN has some extra curb appeal to it for sure.
The exterior showcases one repaint completed in 2013 of the original black. The paint is in good condition. There are some paint chips and flaws when you look closely. The door jambs could have been finished out better. Under the hood is the powerful 3.8 liter turbo-charged V6 engine. This engine was rebuilt in 2013 to stock specifications for reliability / driveability sake. We have receipts for much of the parts and work performed. Brass freeze plugs have been installed. The brake booster was upgraded to the newer GM booster to avoid future issues. The original Grand National power brake system was notorious for problems later in life. Further inspection of the engine compartment will reveal original sheetmetal throughout the firewall, inner fenders and core support. The intercooler piping is polished along with the turbo heat shield.
The interior features factory bucket seating in the original two-tone configuration. The upholstery is in good condition, front to back. The dash displays the original instrumentation and radio, all functional. An aftermarket A-pillar gauge setup has been installed with an Air/Fuel ratio gauge and fuel pressure gauge. The fuel pressure gauge has some LEDs burned out. The dash itself is clean and straight, free of cracking or distortion that can occur with this generation with improper care and storage. There is a dual gauge pod just in front of the shifter with an aftermarket oil pressure gauge, again some of the LEDs are burned out.
The door panels are in decent condition and the door undersides are solid, indicative of a dry climate Grand National. This car needs some odds and ends to really finish it out. The outer window wipes are cracked and worn, in need of replacement. Also the door weatherstripping is worn and cracked in areas. The undercarriage displays original flooring throughout. The front end suspension has been aligned and worked on recently.
The U-joints have been recently replaced along with the tie rod ends with verifying receipts. The rubber frame bushings have been replaced with polyurethane bushings. The frame itself is in excellent condition throughout. Buick's Grand National is equally at home on the track or the street. This example has not been raced. It is a street machine. The GNX-type wheels are fitted with recent radial tires sized at 245/50R16s and 255/50R16s.
