4: Pontiac Grand Prix (1973-1977)
Pontiac had massive success with the GTO and the Firebird during the muscle car era, but there was also the Grand Prix. This big boat of a Pontiac was based on the same platform as the Monte Carlo, and it offered a decent package. The Grand Prix was never worth the same as the Monte Carlo but the current muscle car bubble would lead you to believe it is.
You’ll spend quite a bit of money on a Grand Prix, and that doesn’t even factor in the condition of the car. Even a rolling chassis is going to be a big price tag because of the way that people are trying to snap up these muscle cars.
