How rare is a 68 GTX?
The short answer: a 1968 Plymouth GTX is fairly rare, and the 426 Hemi-equipped versions are exceptionally scarce. Production numbers were limited, and survivorship tends to be low, which boosts interest and value among collectors.
Beyond that, rarity depends on configuration, condition, and provenance. This article breaks down what makes the 1968 GTX notable, how rarity varies by variant, and what collectors look for when assessing these cars today.
What makes the 1968 GTX distinctive?
The GTX was Plymouth’s top-tier performance model for the mid-to-late 1960s, built on the Belvedere/Satellite/Sport Fury platform with distinctive styling and enhanced equipment. In 1968, the model carried forward its performance-focused reputation, but overall production remained limited compared with more commonplace muscle cars, contributing to its rarity in the modern market. Precision manufacturing, documentation, and original drivetrain status heavily influence rarity and desirability among enthusiasts.
Rarity by variant
Below is a concise overview of how rarity shifts by configuration, engine option, and historical availability. The standout factor is whether the car carries the legendary 426 Hemi powertrain, which drives the steepest scarcity and highest collector interest.
- 426 Hemi-powered GTX: the rarest variant, with only a small number produced for the GTX lineup in 1968; survivors are highly prized and sought after by collectors.
- 440-powered GTX (standard or high-performance scripts): more common than the Hemi cars but still uncommon in today’s market; these remain highly desirable but are encountered more often than Hemis.
- Other configurations (primarily 440-driven GTXs that are not Hemi): fewer in number than era-wide averages for identical Mopar muscle cars, yet still rarer than many non-performance Plymouths from that period.
Conclusion: The 426 Hemi GTX stands out as the rarest of the 1968 lineup, while other GTX variants are uncommon enough to be prized by enthusiasts but more frequently found in collections and shows than Hemis.
Survivor numbers and current market presence
Because Chrysler did not publish detailed, configuration-specific production tallies for the 1968 GTX, rarity assessments rely on registries, club records, and auction histories. Generally, only a fraction of the original GTXs are believed to survive in any condition, and a smaller subset remains in numbers-matching, well-documented form.
- Survivor estimates: a smaller portion of the original 1968 GTX population is known to exist today, with many cars in various stages of restoration or in driver condition rather than concours-original state.
- Documentation and provenance: cars with complete build sheets, original drivetrain, and verifiable history tend to be far rarer and more valuable than less-documented examples.
- Market signals: Hemis command the strongest premiums; even non-Hemi GTXs can be scarce, and well-preserved or correctly restored cars often fetch premium prices at auction or through specialty dealers.
Conclusion: Rarity in today’s market is driven by survivorship, documentation, and provenance. The more a GTX aligns with factory-original specifications and includes rare options (especially the Hemi), the rarer and more valuable it tends to be.
What collectors look for in a GTX
For buyers and registries, rarity is closely tied to authenticity and traceability. Key factors include a matching-numbers drivetrain, original build sheet, documented provenance, and a period-correct restoration or well-maintained drivers’ condition. Color combinations, option codes, and verification of historic ownership can all influence how rare a particular GTX is perceived to be in the market.
Summary: In the 1968 GTX sphere, rarity peaks with the 426 Hemi option and with cars that carry solid documentation and matching numbers. While all GTX models are sought after, the Hemis stand as the rarest and most collectible variants today.
Summary
The 1968 Plymouth GTX sits among the era’s more collectible muscle cars, with rarity strongest for the 426 Hemi-equipped examples. Base and other non-Hemi GTX configurations remain desirable but are comparatively more common in the collector scene. For prospective buyers, authenticity, provenance, and documentation matter most when judging rarity and value in today’s market.
