Plymouth GTX Hemi – Price: $150,000+
Introduced in 1967 as a luxury option in the Belvedere lineup, this model was on the same platform as the Coronet. However, it was much more luxurious because of many reasons. Plymouth wanted the GTX to compete with luxury cars of the period. So they installed almost all possible creature comforts along with some special trim on the outside to distinguish the GTX from the rest of the model lineup (via Muscle Car Club).
The GTX was a gentleman’s hot rod with all the options and only one optional engine choice – the mighty 426 Hemi. The 440 Magnum was the standard engine, but if you wanted the ultimate Plymouth muscle luxury, you had to go for the Hemi. Because it was significantly more expensive than the rest of the Mopar muscle car lineup, GTX was never that popular. That makes it pretty rare today.
