12: Rise Of The Dustbuster
Speaking of questionable design choices, there were the Dustbuster-style vans that came out of GM in the early 1990s. The design was about as questionable as possible. GM supposedly dumped billions of dollars into the design of these Dustbuster vans. The end result was a product that consumers were confused about, to say the least (via Jalopnik).
The performance of the Dustbuster vans wasn’t terrible, but the design completely took away from it. GM released a few versions of the Dustbuster van, including an Oldsmobile luxury version. The sales were not what the automaker expected and the Dustbuster vans were quietly discontinued.
