12: Datsun 240Z
Along with other Japanese cars at the time, the 240Z was carving a niche in the marketplace for itself. Although highly regarded as one of the best sports cars to ever hit the road, the 240Z had a lot of shortcomings as well. For starters, the car was prone to rust and a lot of it. This set buyers off early on because they would have to pay to get the rust repaired, oftentimes being too late.

The small dealer network of Datsun was also a problem when it came to getting repairs. Still, the Nissan 240 Z managed to become one of the most iconic sports cars on the road. There was a lot to love about the car and shoppers were willing to put up with the shortcomings.
