After the TR6 this was a disappointment for purists, having gained a roof but lost two cylinders, 500cc and independent rear suspension. It really wasn’t a true TR, until the convertible version arrived in 1979 – those initials simply meant Triumph Roadster. But for all the criticism over these points and the still controversial ‘wedge’ styling, it sold faster than the TR6 had ever done. It’s a much easier car to live with, driving more like a two-seater saloon than a sports car. It’s also by far the cheapest way to join the ranks of Triumph TR ownership.
