9: 1991 Toyota Previa
The Previa is the egg-shaped minivan Toyota sold during the 1990s. The minivan was the most popular segment in the automotive industry at this time, and the Chrysler drove its trio of minivans. Toyota didn’t have much luck with the van they were selling before the Previa and the new van was another try (via Auto Evolution).

Consumers just couldn’t get past the shape of the Previa, which was ugly to say the least. Not to mention the fact that the van was difficult to repair, as the engine was mounted under the front seats. This led to many consumers taking a hard pass on the Previa and rightly so, as the van just didn’t stand up to the competition.
