Description

The Triumph TR6, produced from 1968 to 1976, stands as one of the most celebrated British roadsters of its era. Known for its muscular styling, torquey inline-six engine, and engaging rear-wheel-drive dynamics, the TR6 offered an ideal balance of performance and simplicity. Its straightforward chassis and mechanical layout have long made it a favorite among enthusiasts for customization and upgrades, serving as a versatile canvas for those seeking to blend classic British charm with modern enhancements.

This particular 1975 Triumph TR6 has been modified to elevate both aesthetics and usability. Reportedly repainted approximately two years ago, the interior features brown leather bucket seats, black bedliner-finished floors with rubber floor mats, and a custom faux wood dash insert with white-faced aftermarket gauges. Additional interior enhancements include a MOMO steering wheel, Bluetooth stere head-unit with four speakers, and a custom roll bar with four-point harnesses. The seller reports it has been garage-kept since 2023 and benefits from regular maintenance.

This modified 1975 Triumph TR6 is now offered with numerous spare parts, maintenance and modification documentation, a repair manual, and a clean Georgia title in the seller’s name.
