15: Dodge Aspen R/T
The Aspen is another forgotten Mopar from the 1970s. The car was one of the first downsized models sold by Chrysler during the fuel embargo. The performance of the car when it was new was substandard at best, but with modern enhancements, the car can become a beast (via Hagerty).
There was only 170 HP from its 360 V8 engine, which was very scaled-down at the time. There is a lot of potential that this car has with the right owner. The Dodge Aspen R/T is perhaps one of the most forgotten cars from this era at Chrysler, and it never sold well.
