For Sale: 1986 Buick Grand National in Farmingdale, New York

1986 Buick Grand National for sale! Few cars define an era the way the 1986 Buick Regal Grand National does, and this all-original, garage-kept example, showing 78,532 miles, is one of just 5,512 built for 1986. Finished in the Grand National's signature black with T-tops, it pairs its menacing presence with a performance-built drivetrain: the intercooled 3.8-liter turbocharged V6, now producing a claimed 300 horsepower through a custom-built 2004R transmission with a custom torque converter by "Turbo Dave," backed by turbo hypereutectic pistons, 30 PSI injectors, a dual roller timing chain, stainless steel valves, roller rockers, a 3-inch down pipe and polished stainless dual exhaust, a Kenne Bell cold air intake, a Posi-Trac rear end, Bilstein shocks, and a performance chip. The car was repainted in single-stage acrylic enamel - no clear coat - to resemble the factory finish by Al Furnish of Al's Hot Rod Barn in Aurora, Indiana, and it rides on new BFG Radial T/A 235/60R15 tires fitted in September 2026, alongside new front brakes, a new alternator, a new A/C compressor, and a new battery from the same month. Inside, the all-original interior retains its digital dash, complemented by a VDO center gauge pod and a Kirban Performance trunk and hood liner kit.What sets this car apart, beyond its build, is its collectability and its paperwork. The Grand National is the definitive American performance car of the 1980s - a turbocharged V6 Buick that outran the V8s and Corvettes of its day - and 1986occupies a special place in that story: it was the first year of the intercooled turbo engine, and with only 5,512 produced, it is far rarer than the 20,193 built in the final 1987 model year, the year before the legendary GNX closed the book. Documented, well-kept examples like this one, with their original window sticker, dealer invoice from Keane Buick-GMC, 1986 Buick Buyer's Guide brochure, and GM factory service manuals all conveying with the car, are the ones collectors chase, and they are the ones that have appreciated into blue-chip territory as the market has recognized the Grand National as a true modern classic.
