9: Oldsmobile Achieva
Oldsmobile was a shell of its former self by the 1990s and the brand was littered with recycled GM vehicles. The Achieva was a small sedan that had skirts over the rear wheels and looked generally dated. The powerplant was shared with other sedans from the GM lineup as well so there wasn’t anything special.

The Achieva was sold in a four-door and two-door combination although most of us have forgotten this car existed. The typical GM quality issues were present on the Achieva which deterred a lot of buyers from GM cars around this period.
