The General Motors G platform (also called G-body) was an automobile platform designation used for mid-sized rear wheel drive cars. It made its first appearance in 1969-1972, adapted from GM's A-body, and reappeared from 1982 to 1988.
This family consisted of the Buick Regal, Chevrolet El Camino, Chevrolet Malibu, Chevrolet Monte Carlo, GMC Caballero, Oldsmobile Cutlass Supreme, Pontiac Bonneville, and finally the Pontiac Grand Prix.
I've always likes the super strict linear quality of the range, really answers the question about how square a car design could possibly get. Their simple surface design really opens up more creative possibilities with the paint, an almost blank canvas.
They were designed with a small wheel well, ideal for 13 inch wire wheels, such a iconic look. They preform great with hydraulics and hopping thanks to its lightweight V6 engine.
Probably a cheaper entry into owning a lowrider, these heavily plastic detailed cars can be susceptible to cracking unlike their older GM metal counterparts.
