27: Pontiac Catalina 421 Super Duty
Before the GTO became the breakout hit it did, Pontiac marketed a slightly different performance car. The Catalina 421 has been forgotten and overshadowed by the GTO, but this was a serious performance car from the time. The Catalina had the styling cues that you’d expect from a Pontiac from this generation. The 421 was a performance powerhouse and propelled the car with authority, yet still had the comfort of a family car.

Pontiac was very much into space like much of the world in the 1960s with the Catalina. This car has become a rarity in the muscle car market. There were fewer than 180 examples that were built with the 421 engine, and a lot of the cars that are still around are rusted out and old.
