Finding a classic that is equally comfortable on the road or the racetrack can be challenging. However, this 1971 Triumph GT6 seems to have those bases covered. The mechanical upgrades would make it a weapon at a track day, while the seller states that it is civilized enough to prowl our streets without issue. The seller has listed the sweet Triumph here on Facebook Marketplace in Rancho Cucamonga, California. They set their price at $18,000 for a classic that is a turnkey proposition.

Based on its existing Spitfire, Triumph released the GT6 in 1966. A Mk II version arrived in 1969, with the Mk III representing the final update in 1970. Our featured Mk III left the Canley line in 1971, and much has changed since that day. The Blue paint gracing its panels isn’t from that year’s color palette, and bears a striking resemblance to French Blue. It holds a healthy shine, although close inspection reveals a few minor imperfections. However, since this classic spends its life on the racetrack, its presentation is easily acceptable. The panels are quite straight, and the images reveal no evidence of rust. The seller removed most of the trim during their build to reduce weight, while the VTO alloy wheels are wrapped in new Toyo Proxes R888 tires.

Tilting the hood forward reveals this British classic’s beating heart. It retains what I believe is its correct 1,996cc six-cylinder motor, although it’s a safe bet that it produces more than the 95hp quoted by the manufacturer. The seller added a roller rocker valve train for longevity, along with a larger oil pan, a windage tray, a remote oil filter, an oil cooler, and an aluminum radiator. They handed the motor to a professional shop, who built it to provide a compromise between street and track duties. The engine exhales through headers and a single exhaust with additional mufflers for street use. The suspension incorporates adjustable coilovers, while the brakes are upgraded slotted discs. The power feeds to a 3.89 rear end via a 1973-vintage Triumph TR6 manual transmission. The seller states that the car is registered and roadworthy, and that the motor has only clocked around five hours since the build. Potential buyers can consider it a turnkey proposition.

The interior reflects this classic’s racing history. Anything unnecessary is long gone, including the carpet, seats, and upholstery. The driver sits in a lightweight aluminum race seat, with the ½-cage providing protection if the car finishes up shiny side down. They face an aluminum dash fascia housing the critical gauges that monitor the Triumph’s health and temper. Is it luxurious? No. Is it practical? It certainly is for the track. However, I would probably add seat padding for street use, because things could become uncomfortable fairly quickly.

This 1971 Triumph GT6 Mk III won’t appeal to everyone, but no classic can achieve that feat. However, it presents well, and the mechanical upgrades should deliver substantial performance gains. Add some padding to the seat, and it would be enormous fun if the person behind the wheel points it at a ribbon of twisting tarmac. The seller’s price looks extremely competitive, providing an affordable entry into the world of motorsport. If you’ve been considering dabbling in that hobby, could this GT6 be a contender?
