All of my cars have been two doors. The first two were only two seaters as well (no back seat). Currently I'm driving a 94 Mustang GT with a few minor mods, so I can appreciate one of your shopping options.
However, my wife drives a mini-van. I had to do it. As much as it pained me I just had to. When you have a young child in a booster seat and two babies in car seats you have to have a roomy vehicle that is easy to climb in and out of. Hey, at least if I ever decide to go to a KH, I'll fit right in. Yeah right!
