Price My Classic

During the late 80s there were a few iterations of what GM made called the 'G-Body' including the Cutlass, the Monte Carlo, and the Regal. The Grand National was what you get when you take the Buick Regal, drop a V6 in it and add a turbo, making for one of the greatest sleeper cars made from the factory in car history. This Grand National has been taken above and beyond the call of being an unassuming performance Machine by rebuilding the original 3. 8 liter V6 to handle the boost coming from the much larger than stock turbo, which is pushing close to 18 psi of pressure through an intercooled setup featuring a larger wastegate and a Godzilla blowoff valve. The hopped-up beast of a powerplant is backed by a 200R4 4-speed automatic transmission with electronic overdrive which has also been beefed up to be able to handle the power this car is putting to the wheels. This combination at engine and trans makes for a street drivable car that can accomplish the 1/4 mile in the 10 second range. Walking around the car, anyone will notice the car has some custom work done to its appearance as well with...

1982 was the first year of this now iconic nameplate, and only 215 were produced. In the current unofficial registry, there is not a vehicle with a lower production number than this one! This Buick is powered by a naturally aspirated 4. 1l V6 paired with a 4-speed automatic transmission. The vehicle has lived a pampered life, having only travelled just over 34,000 verified miles, but the current owner wanted to bring it to better than factory condition.

The Buick was completely stripped down and received corrective bodywork to have the panels line up better than Buick initially had. The engine was completely torn down and rebuild to factory specs, as was the transmission. The seller wanted this vehicle, potentially the first of its kind, to be in better-than-new condition for future owners to fully enjoy The paint looks deep enough to get lost in, the suspension is tighter than some modern cars, and the engine runs...

This car left the factory as a 1987 Grand National and has been upgraded to GNX specs and then some. The car received a complete overhaul that was completed less than 5 years and 5000 miles ago. Built by Weber Power Products in Ohio this Grand National was brought up to GNX specs and then some as both performance and handling were improved. Every inch of this car has been gone over and there is no detail that has not been taken care of. It is one of the nicest Grand Nationals that we have seen. The Grand National is about as popular as any car that we get at Gateway Classic Cars. Literally every week someone contacts us to see if we have a Grand National in stock. Grand Nationals were the kings of the dragstrip in their day and proved there is a replacement for displacement. And they-re still a hoot to drive. The Grand National and its many variations boast a fervent owner group who stick together and really enjoy their cars -' it-s easy to understand...

1987 was the final year for the production of the Buick Grand National. The owner had the foresight to purchase this car, and store it away. This is why there is less than 3300 miles on the odometer. This 1987 Buick is truly a time capsule, with it --80-s styling; not an airbag or CD changer in sight, relatively tall tires, rear drum brakes, square-rigged interior lines, and a tiny equalizer tone control in the audio system. The interior still looks brand new; the Lear seats are pretty comfy, and the GN-spec gray cloth upholstery is grippy, a good thing because there's not all that much side bolstering to keep you planted during cornering maneuvers. Under the hood is the stock 3....
