Plymouth GTX
The Grand Turismo Exterminator or GTX isn’t precisely a long-lost or forgotten model. But it needs to get the attention it deserves in muscle car history. They based this model on the same platform as the Coronet or Roadrunner. However, it was much more luxurious with a 375 HP engine standard. The GTX was a gentleman’s hot rod with all the creature comforts (via Muscle Car Club).
It had only one optional engine choice: the mighty 426 Hemi. The GTX was significantly more expensive than the rest of the Mopar muscle car lineup. This means it was never popular and is rare today. However, the GTX was gone in 1971, keeping it from being a disgrace like other muscle cars. That is why the 1971 GTX was the last of its breed. And most car fans believe it’s a fantastic muscle car that deserves recognition and respect.
