37: Mercury Topaz
Sharing a platform with the Ford Tempo, the Mercury Topaz was a budget-oriented option for consumers. The problem was that the car was not much different from the Ford. In fact, the two cars were completely the same and the consumers could tell. If Mercury had offered something a bit more unique, the Topaz may have sold better (via TTAC).
But the fact that it had shoddy building quality and a lack of reliability just made consumers go to the competition. This was around the time that the Japanese automakers were continuing to get better. The Topaz was criticized for having the same design as the Tempo and not offering anything as an improvement.
