10: Isuzu I-Mark
The Isuzu I-Mark is a car that you probably don’t remember sold in the 1980s. The wider recognized version of the I-Mark was the Geo Spectrum. Both cars were sales flops for the automaker, and Isuzu would exit the passenger car market shortly thereafter. Reliability was scarce on the I-Mark and the Spectrum, which caused consumers to revolt (via Hagerty).
There were some unusual features about the I-Mark, one of which was the Lotus-tuned suspension. The I-Mark could handle the twists and turns of the open road well. Isuzu also managed to incorporate a substantial amount of standard features into the I-Mark. But the internal competition from GM meant Isuzu couldn’t supply its own dealerships.
