11. 1971 Corvette ZR2
The 70s were a tough time for muscle car enthusiasts as gas prices and emissions laws were causing automakers to reduce horsepower dramatically. Although the 70s were the start of GM de-tuning their engines, the ZR2 somehow made it past. This Corvette was one of the few models that got to keep all of its horsepower. The big motor gave the ZR2 a whopping 460 horsepower, and there were options with the ZR2. The convertible ZR2 is the rarest as only two were produced. There were only 10 coupes produced as well, making this one of the rarest Corvettes.
If you’re lucky enough to get a hold of a ZR2, you’ll be treated to one of few Corvette models that managed to slip through the cracks during the smog regulation. This was a tough time for GM, and it’s a wonder the ZR2 managed to slip through the cracks.
