To me, the most important aspect of a car, has to be the feeling, or, as some people say, the ability to make you smile, because, that's what really catches you.
I mean, sure, nobody wants to drive a car that's ugly, but have a really nice looking car, which has no feeling, no emotion, all the visual is... pointless, because when you drive, you don't enjoy it, you don't have a good time while doing so, you don't feel this need to take the car at night for a drive, just to drive around.
A rough comparision that i made recently was between the new Golf GTi and the new Civic Si... the Golf GTi wins in 90% of things against the Si, it's better looking, better built, more comfortable, faster and better on stuff you get for the price you pay. Although, the Si wins in 10%, and those 10% is the feeling... and for me, if a car doesn't have that 10% the Si has... i can't see myself driving it.
You see, i might over-explain here, but what i mean is that driving feeling goes beyond logic. It may not make you buy one, if you really need to rely on logic when you buy a car, but it sure will make you think/dream/wish you had them.
