The Triumph TR4A, introduced in 1965, was a significant update to the Giovanni Michelotti-styled TR4. The most important change was the new independent rear suspension (IRS) system, which greatly improved ride quality and handling. While most cars received the new IRS, Triumph also built a number of TR4As with the old TR4's solid rear axle, primarily for the benefit of racers who preferred the older setup.
The TR4A retains the classic good looks of the TR4, including its roll-up windows and optional "Surrey Top" targa roof. It's powered by the same 2138cc inline-4 engine, providing lively performance for its era. Today, collectors appreciate the TR4A for combining the pure TR4 aesthetic with a more comfortable and capable chassis.
With an average sale price around $24,000, the TR4A market is quite accessible. The wide price range, from under $1,000 to over $52,000, reflects the vast difference between neglected project cars and professionally restored examples. Well-sorted driver-quality cars offer a fantastic value for anyone looking to own an iconic British roadster.
Buying Tips
- Check for rust thoroughly, especially in the floors, inner and outer sills, and around the rear suspension mounting points, which are unique to the IRS cars.
- The independent rear suspension is a key feature. Inspect the driveshaft universal joints, differential mounts, and lever-arm shocks for wear and leaks, as repairs can be involved.
- Verify if the car has the independent rear suspension or the less common solid rear axle, which was a factory option. The chassis number prefix CTC indicates an IRS car, while CT denotes a live axle.
- The 2.1-liter engine is durable, but check for low oil pressure (it should be at least 50 psi when warm) and signs of overheating, a common issue for Triumphs of this period.
Prices range from under $1,000 for major projects to over $52,500 for top-tier, restored examples.
