I would recommend that you buy what makes you happy, and that you ignore those who criticize your choice of car based on their perception that it is “a chick car”.
For many years I have observed that some cars just seem to appeal more to women than to men, with two examples being the old “original” Barracudas with the huge rear window, and the “new Beetle”. However, just because a car’s styling might appeal more to women than to men does not automatically emasculate a man who drives one of these cars.
Bear in mind that those who feel compelled to make statements like “the Miata is a chick car” are essentially very insecure about their own masculinity. In fact, I think that it could probably be argued that you are simply more secure in your masculinity than they are if you don’t feel threatened by driving what they call “a chick car”.
Buy what you like, and ignore those who are terminally insecure.
