16: Pontiac Firebird (1970-1981)
The second-generation Firebird was inhibited by a painfully slow powerplant due to the new emissions laws taking place. This example of the Firebird was by far the slowest generation of the GM F-Body that was ever made. Aside from that, the prices for these lowly cars have gone off the rails, and unless you’re Burt Reynolds, it’s just not worth it.
That’s not to say that the second-generation Firebird or Camaro are bad classic muscle cars, but they aren’t worth the current prices. Pony cars have evolved a lot over the decades and the middle of the 1970s was a hard time for all domestic automakers.
