Eighth-worst: 1982 Cadillac Cimarron
The 1982 Cadillac Cimarron was a symbol of what was wrong with GM in the 1980s, an effort to compete with BMW by redecorating the front-drive, four-cylinder Chevrolet Cavalier and calling it a Cadillac.

Edmunds.com called it "a self-inflicted wound that nearly killed Cadillac."

The car was an embarrassment from the start, Oldham says, and "the press was all over it." It underscored the difference between BMW and Mercedes, on the one hand, which understood what luxury car buyers wanted, and Cadillac, on the other hand, which did not.

Cadillac "was on the downswing, almost to the point of extinction" until cars such as the CRS and SRX began to revive the brand, Oldham says. Now, Cadillac is trying to further redefine itself as a viable competitor with the ATS.
