Unlike other cars with unusual and “modern” (for the time) designs, the 1975 Triumph TR7’s design was not its undoing. The big problem with this car other than its strange shape was its construction. The entire line of TR7s and TRs (the eight-cylinder version) had manufacturing defects and design flaws that quickly became apparent.

Electrical problems became the most obvious problem as many of the TR7s had short circuits often. This also led to mechanical failures of critical systems. Plus, basic equipment parts, like timing chains, would snap since they were made with inferior craftsmanship. Essentially, anything that could break in the TR7, did break in the TR7.
