I'm 18 and have really only had 4 cars to myself so my list is pretty long. I guess here are the most interesting parts.
I've never owned anything FWD, AWD or 4x4.
I've never owned anything with a hatch.
I've never owned anything with less than 6 cylinders.
I've never owned a car with two doors.
I've never owned anything with an screen inside of it.
I've never owned anything with a fold-down rear seat.
