15. 1971 Plymouth GTX 426 Hemi
The GTX was a gentleman’s hot rod with all the top options including nice interior and exterior details. But it only had one optional engine choice, the mighty 426 Hemi. The 440 Magnum was the standard engine, yet if you wanted the ultimate Plymouth muscle luxury, you had to go for the Hemi. However, because it was significantly more expensive than the rest of the Mopar muscle car lineup, the GTX wasn’t popular, so it is very rare today.
In the early ‘70s, when all muscle cars started to lose power and torque figures, Plymouth discontinued the GTX. So in 1971, they ceased production to keep it from being a disgrace to its fire-breathing predecessors. And that’s why the ‘71 GTX is the last of its breed as well as a fantastic muscle car.
