16: Plymouth Volare Roadrunner
The Roadrunner is one of the most iconic muscle cars ever released, but a few years later there was also a budget-oriented version of it. The Volare Roadrunner never achieved the sales success of the original car but was still quite the thing to behold (via Hagerty).
The styling of the Volare was bland, but when you bring it into the modern era, you can make this car look great. There are plenty of aftermarket accessories that you can get for this car, and the engine is versatile. If you want an affordable Plymouth muscle car, this is a great option.
