6. BMW 5-Series Gran Turismo
We’re still unclear what BMW had in their minds when they created the 5-Series Gran Turismo model. This, third body style for the 5-Series, was not only completely unnecessary but also downright ugly. It looks like regular 5-series had swallowed an elephant. The higher roofline and rear hatch door definitely didn’t help the aesthetics (via Auto Express).
As expected, the sales of this model were terrible. People just didn’t find it attractive or more practical than the sedan (or wagon). BMW stubbornly introduced the 3-Series with the same feature but since has retired both models and moved on.
