Few cars from the 1980s carry the mystique of Buick's turbocharged Regal, and the Grand National sits at the top of that legend. This particular 1987 example takes the story in a thoroughly modern direction, swapping the factory turbo V6 for a Chevrolet LS3 V8 while wearing the aggressive look of the limited-edition GNX. Listed by Earth MotorCars of Carrollton, Texas, the blacked-out coupe shows just 1,111 miles and is offered at $189,900 or best offer.A clean side profile shows the two-door Regal body and blacked-out trim.At the heart of this restomod is GM's LS3, the 6.2-liter aluminum V8 that powered the C6 Corvette and a generation of Camaros. In factory form it produces well over 400 horsepower, a dramatic leap from the 245 horsepower the original 3.8-liter turbo V6 made in 1987.
