My wife is pregnant i got a few months to look for a used or new "preferred new" car with AUTOMATIC. Probably the 5 doors liftback yaris. I just love the yaris feel and look. Honda fit is way overprice, Nissan Cube is....don't know yet, Aveo - forget about that, Kia Soul---eehhh thinking about it. Scion XD - my friend got one, don't know what else to look for.
Anyone got any ideas? should i trade it in? or sell it private? i'm trying to save every penny at the moment now for the baby.
