21: Infiniti J30
The Infiniti J30 is a classic example of a luxury car brand that really didn’t cut it. The Infiniti brand has never been a success for Nissan, and the early models were even worse. There were a few things drivers didn’t like about the J30. The exterior design got a lot of flack for the overtly rounded corners and deck lid (via The Truth About Cars).

The performance wasn’t especially impressive and interior quality was shoddy at best. The interior proportions were also uncomfortable when you thought about what the car offered. To many potential consumers, the J30 looked like the Nissan Altima was already on the market at the time.
