1981 Pontiac T1000 (Worst)
There was a point in time when GM went through a phase of giving new vehicle nameplates a futuristic twist. The eighties were a new era after all, and the T1000 was one of the first brand new models. The car was a subcompact that shared its platform with the Chevrolet Chevette, which was the best-selling subcompact car in the United States at the time. The T1000, on the other hand, didn’t fare well because it was not accepted by Pontiac loyalists (via Classic Car Database).
The Pontiac T1000 did not catch on with consumers, and the sales were remarkably slow. The car was eventually discontinued and replaced by the Daewoo-designed LeMans subcompact. These early GM subcompact models were not the most appealing cars on the road. But, the automakers in the U.S. had to try and do something to compete with foreign competitors.
