BMW M cars continue to be among the most desirable performance models currently on sale in the market, with the famous BMW M3 widely regarded as one of the most influential sport sedans since its first incarnation. The two-door counterpart, the BMW M4, also comes to mind when buyers think of a performance two-door currently in production by a German brand. These two BMW M models share a lot in common, but are there any significant differences between the BMW M3 and M4 aside from how many doors they have?
