BaT Auction: 8k-Mile 1986 Buick Grand National

This 1986 Buick Grand National was delivered new to Schepel Buick, Inc. of Merrillville, Indiana, and was acquired by the seller in 2021. Power comes from a turbocharged and intercooled 3.8-liter V6 paired with a four-speed automatic transmission, and the car is finished in black over two-tone gray and black fabric. Factory equipment includes air conditioning, an AM/FM cassette stereo, a power-adjustable driver’s seat, cruise control, power door locks and windows, a security system, and 15” alloy wheels. A TurboTweak computer chip has been installed, and recent maintenance is said to have included a brake fluid flush, an air-conditioning recharge, a power-antenna repair, and the installation of a replacement brake booster accumulator ball. This Grand National shows 8k miles and is offered with manufacturer’s literature, a window sticker, the removed computer chip, service records, a clean Carfax report, and a clean Ohio title in the seller’s name.

The car is finished in black with matching trim and equipped with front and rear spoilers along with Grand National badges on the fenders and trunk lid. The seller notes that a paint correction procedure and detail were recently performed. Flaws include dents in the driver-side door and hood, a paint blemish on the passenger-side door, scratches on the rear bumper, and chalky bumper fillers.

Polished 15” alloy wheels feature black accents and are mounted with BFGoodrich Comp T/A tires. Stopping power is provided by front disc and rear drum brakes, and the seller notes recent service that included a brake fluid flush as well as the installation of a replacement brake booster accumulator ball. One of the wheels is said to have been replaced by the first owner and shows a 1988 date code.

The cabin features front bucket seats and a rear bench upholstered in black fabric with gray inserts and embroidered “turbo-six” logos on the front headrests along with a gray dashboard, matching door panels, and black carpets. Amenities include air conditioning, cruise control, a power-adjustable driver’s seat, a Delco AM/FM cassette stereo, power windows, a factory security system, and a carpeted trunk.

A leather-wrapped steering wheel frames a horizontal 85-mph speedometer and a fuel level display along with a digital tachometer and boost pressure gauge. The five-digit odometer shows 8k miles, approximately 150 of which have been added by the seller.

The turbocharged and intercooled 3.8-liter V6 was factory rated at 245 horsepower and 355 lb-ft of torque. A TurboTweak computer chip has been installed, and the seller notes a recent oil change. Maintenance in 2014 reportedly included replacement of the fuel pump, rear main seal, and oil pan gasket. The catalytic converter was reportedly removed prior to the seller’s acquisition, and was subsequently replaced with a unit that was missing the heat shield. The removed factory computer chip and a spare hollowed-out catalytic converter with a stock heat shield will accompany the vehicle.

Power is sent to the rear wheels through a four-speed automatic transmission with overdrive, and corrosion on the suspension components is noted by the seller. Additional underbody images can be seen in the gallery below.

Manufacturer’s literature is included in the sale along with a 1990 recall notice for the brake combination valve and a ‘gold’ award reportedly won by the car at the 2021 GSCA Nationals in Bowling Green, Kentucky. The included window sticker shows initial delivery to Schepel Buick, Inc. of Merrillville, Indiana, as well as factory colors, equipment, and a total price of $17,601.

The Carfax report shows no accidents or other damage and displays history in Ohio beginning with the first entry in 2014.
