Car History

The For Triumph TR4 is a sports car built in the United Kingdom by the Standard For Triumph Motor Company and introduced in 1961.

The new TR4 body style did away with the classical cutaway door design of the previous TRs to allow for wind-down (roll-up)

windows (in place of less convenient side-curtains), and the angular rear allowed a boot (trunk) with considerable capacity

for a sports car.
