37: 1986 Pontiac Grand Prix 2+2
The GM G-Body platform was dominant in the 1980s and one of the most popular automotive platforms GM ever sold. When it came to a unique offering, the Pontiac Grand Prix 2+2 built on the success of the already dominant platform. A unique aerodynamic design separated the car from its platform mates (via Barn Finds).
It was this bubble-back design that made the Grand Prix 2+2 stand out from the crowd. There are very few cars from this era that had such a unique look. Sadly, the bubble-back Grand Prix never managed to catch on with consumers and sales numbers were very low. You’ll seldom see one on the road anymore.
