That last paragraph is so full of FAIL its epic!
The Mustang has four seats with LATCH! Why do people have to confine themselves in these little archetypes and cater to everyone's silly expectations. Live a little enjoy life!
When I'll need something with more then two doors the answer is, Mitsubishi Lancer Evolution, Subaru STI, or 4 door M3. You don't have to trade in your likes and your personality for 'practicality' There is plenty of ways for everyone to be happy! while maintaining your own persona.
Sorry just had to rant a little I've seen too many times what giving up something you really want or like does to someone I hate when I hear people head down that way.
Who says you have to own 1 vehicle? Buy a Mustang, an SUV or something similar, and toss in a motorcycle for good measure. Then you'll have all angles covered. I'm with ya.
