14: Pontiac Trans Sport
As with most of the rebadging that GM did during the 1990s, the Trans Sport was another indication of that process. This time instead of a dustbuster-themed van, you had a sport-themed van. The styling of the Trans Sport was horrible to look at and the second generation of the van got one of the worst crash test ratings in history (via Motor Trend).
Sadly, GM tried to rebrand this van as Montana later on, but even that wasn’t enough to bolster the sales of the car. It would appear that most people just aren’t willing to pay a premium for something that lacks both style and substance.
