I have a Scion xD (made by Toyota) that I bought about a year ago.
It's a little economy car and gets great gas mileage (32-34mpg in the city).
I was going to buy a used Toyota Matrix, but the xD was the same price and brand NEW!! It was about $15K.
It is small. I have 9 and 11 yr old kids and they fit fine in the backseat though. I just can't carry a cooler in the back like I used to take to the store, but I bought an insulated bag that works fine.
Good luck
