Well, please don't face punch me, but I think having "too small" a car makes for being cheap under some circumstances too.
I am not talking about a Sedan vs a SUV, but micro cars. I carpool with a co-worker, and we are more often 3 than 2 fully grown adults on our 40 miles to this research lab we work at. I drive a Hyundai i30 from 2008, which I consider mustachian enough, and fits 4 adults with dignity. He has a Toyota Yaris, bought exclusively for getting to work, and it is not possible to assort one's body properly in there. I dread the days it's his turn to drive, although we both profit.
Just a minor thing, but you can overdo it. If you need a car, buy one that fits real people! (No, I am not fat :-) )
