17: 1986 Pontiac Grand Prix 2+2
The Pontiac Grand Prix 2+2 is another well-regarded GM G-Body coupe. It’s perhaps the rarest in the bunch due to its relatively limited production. Style-wise, the Pontiac Grand Prix 2+2 was designed to be more aerodynamic on the race track. In fact, the car was originally designed specifically for NASCAR, but a consumer version was put into production (via Barn Finds).

The main difference from an ordinary GM G-Body was the bubble back rear window. The front fascia was also vastly different from the main model. Rounded corners were used to try and alleviate some of the car’s rough edges. All-in-all, the design of the Grand Prix 2+2 was different than you’d expect from this era.
