From a woman's point of view, I have to say that a majority of women probably only buy a Mustang, as opposed to other cars because it's what is 'popular' for the time. A girl sees a Mustang that she likes or, as Dragon put it, is "cute" and she's like "OOHHH I want THAT one!"
Would I go over to the "Dark Side" and purchase a Mustang? HELL NO... Why? Because I find nothing remotely "cute" about it. I admit that the 03 and 04 Mustangs were pretty good looking cars... But I hate this new body style. The rear is too "blocky" looking for my tastes and the tail lights are way too big. The front is too plain looking and there's nothing going on to interest me. The V6's front end is boring and the V8's front end has those two HUGE "fog lights" in the middle of the grille. Heck, the "pony package" looks better with the smaller lights in the grille, but what was the point of having "fog lights" if they are going to be on the same level as headlights??
I was, am, and always will be a Camaro girl. Camaro just makes me think of raw muscle! Corvettes are quick and aggressive, but there is just something about the Camaro that makes it different.
Oh, and I may have a V6 now... but trust me. This girl IS getting a Z28!!!
