"Triumph's enduring TR series was developed gradually, beginning with the TR2, which evolved into the TR3 and gained a new Michelotti shape to become the TR4, which in turn received a new chassis with independent rear suspension to spawn the TR4A. For the TR250, the body and chassis of the TR4 were mated with a 2.5-liter version of the company's straight-six. Breathing through twin Stromberg carburetors for the U.S. market, performance was similar to the TR4's. Visual differences included nose striping, some black paint on the grille and other detail changes.

"With the loss of the Austin-Healey 3000, BMC decided to replace it with a six-cylinder version of the MGB. With a big three-liter six over the wheels and torsion bar front suspension, the new car [the MGC] was more of a grand tourer than an out-and-out sports car. It could eat vast stretches of highway effortlessly, but after a mixed reception from the motoring press, sales never really took off."
