my wife and i wear matching sweaters.. a car is not big deal.
i would file it under "I". as in I could give a flying rats ass what everyone thinks.

on the bright side, it would be nice during car maintenence..if you mess up, you have anothe exact same car you can use as a sort of roadmap to get you back on course. like that brilliant moment where you thought you could remember where all the wires went.
