5: Dodge Dynasty
The Dynasty was a square-bodied sedan that didn’t look like anything else on the road. There is a good reason for that, as Chrysler was trying to appeal to luxury shoppers. The problem is that the Dynastic was not the luxury car that most hoped for. In fact, the Dynastic was undersized when compared to the competition (via Consumer Guide).

It also didn’t help things out that Chrysler sold a carbon clone of the car. The Dynasty seemed to sell well initially, but things tapered off once buyers knew of the car. There were much better options drivers could purchase for a lot less money.
