Yeah, when I drove the last few cars for 7-10 years, it said "she's frugal." And I didn't care any more about coolness and cars then than I do now.
You have it wrong. Uggs are cool. Yet I think they are ugly and won't wear them. It's all the rage to have board straight hair. It would look ugly on me, so I stick with curly. I have driven plenty of cars that lacked the "cool factor." But when I looked at them, I didn't think, "U-G-L-Y", so I was content. Not cool, but content.
Scions are ugly to me. Flexes are ugly. Hummers are ugly. So are minivans. I imagine the people driving them don't think they are ugly. Maybe when they look at my vehicle, they wonder why anyone would buy THAT?

But I don't care. I didn't pick it for coolness. It had to fit my short legs, be comfortable, be reliable and the only thing I asked for in "styling" was that it not be ugly. Ugly is not synonymous with uncool. And cool isn't the same thing as good-looking.
If (like me) you don't give a rat's red rear end about "cool", you can still cringe upon seeing something you perceive as ugly. And you can still say, "I may not be picky about cars, but I draw the line at buying/driving a butt ugly one."
I get why so many people like minivans. But the truth is, many others find them ugly. I don't care that it's a mom wagon. I'm a mom and I haul DD and her friends, so anything I drive is a mom wagon unless I'm alone in it.
Some dislike minivans because they maintain they are "not cool." I am not in that camp because I don't care about coolness. I do, however, care about UGLY. I'm in the "I can't drive it because it's too ugly" camp. I would drive it if it was all I had, but I have a choice, so why not choose something NOT ugly? Why not wear a pretty shirt or at a minimum, a nonoffensive one that does not make people avert their eyes? Why not comb my hair instead of wearing a rat's nest? Just because you have SOME standards (nothing ugly, thanks) doesn't mean you require "cool".
