This 1987 Buick Grand National was acquired by the seller out of Arizona in 2007 and was previously listed on BaT in April 2022. Work during current ownership is said to have consisted of modifying the 3.8-liter V6 with a GN1 Performance long-rod stroker kit, a Super Extreme intercooler, a Super Extreme radiator, custom exhaust headers, a 3″ downpipe, a cold-air intake, and an Aeromotive fuel pump regulator in addition to rebuilding the transmission with an Art Carr 9” torque converter, a non-lockup sleeve, a hardened input shaft, and a heavy-duty transmission cooler.
The car is said to have been refinished in black in 2020, and replacement emblems were affixed to the body at that time. Exterior details include a sculpted hood, a sunroof, sport mirrors, tinted windows, a rear window defogger, and a three-piece rear spoiler. The headlights, taillights, and side markers were replaced in 2022.
Staggered-width 20″ Weld Racing wheels with black spokes and chrome lips are mounted with Pirelli P Zero tires measuring 245/35 up front and 275/35 out back. The car has reportedly been fitted with Aldan American front and rear adjustable coilovers with an upper shock-mount reinforcement bar as well as Hotchkis upper control arms, and a Baer disc-brake conversion at all four corners with a 1″-bore primary cylinder. Service in 2021 included the replacement of the bushings, ball joints, steering components, tie rods, and brake lines.
The cabin was refreshed in 2021 and work during that time reportedly consisted of replacing the power door lock and window switches in addition to reupholstering the seats in two-tone black and Sand Gray cloth. Appointments include air conditioning, cruise control, Grand National-branded floor mats, and a short gear selector handle. The Pioneer Mixtrax stereo features a flip-up touchscreen and is connected to a DS18 sound system with a Memphis Audio MOJO Mini subwoofer box located in the trunk. There is a crack in the dash.
