4. Plymouth GTX
Most car enthusiasts know about Roadrunners or Barracudas, but only a few remember the GTX. They based this model on the same platform as the Coronet or the Roadrunner, but it was much more luxurious. It also produced 375 HP as standard. Plymouth wanted the GTX to compete with the luxury cars of the period.
Ford decided to install all the possible creature comforts, along with special trim on the outside. They wanted to distinguish the GTX from the rest of the model lineup. The GTX was a gentleman’s hot rod with all the options and an attractive interior. It had several exterior details, but only one optional engine choice: the mighty 426 Hemi.
The 440 Magnum was standard, but if you wanted the ultimate Plymouth muscle luxury car, you had to go for the Hemi. Because it was significantly more expensive than the rest of the Mopar muscle car lineup, the GTX was unpopular, so it is rare today.
When the early ’70s arrived and muscle cars started to lose power and torque figures, Plymouth discontinued the GTX. They stopped production in 1971 to keep it from being a disgrace to its fire-breathing predecessors. The 1971 model went out with a bang, though. When they added a standard 440 V8 engine, it could do 0 to 60 mph in 6.5 seconds, which was a respectable figure for the time.
