1: BMW M2
Perhaps one of the least well-known cars on this list is the M2. Released during the economic depression, this was a way for BMW to release an entry-level car. The M2 had a lot going for it, from its compact size to its fun design. But BMW left out several crucial features that many luxury car buyers have come to expect. The M2 was missing many interior functions.
With a few more features to boast, it would have done a lot better in terms of sales. There was also a convertible version of the M2, which also boasted a good amount of performance and functionality. Overall, the M2 is a car that can still provide you with a good amount of enjoyment.
