1970 Chevrolet Monte Carlo SS
In the late ’60s, the Monte Carlo was a handsome coupe-only car with V8 engines, a nice interior, and decent interiors. Even though most of Monte Carlos came with smaller V8 engines, bought by the people concentrated on the luxury aspect of this model, there still was one crazy muscle option with the SS 454 package (via Hemmings).
This version was a true full-size muscle beast with a monstrous 7.4-liter V8 engine. That pumped 360 HP and propelled the heavy Monte Carlo to extraordinary 0 to 60 mph times. For just $420 above the base price, buyers could get this trim level, which transformed this coupe from a somewhat lazy cruiser to a quarter-mile beast. However, only around 3,800 people decided to do so. The Monte Carlo SS 454 remains one of the rarest luxury muscle cars ever produced.
