I have had several much more expensive cars, but I love this one the most. The gas mileage is great and it is small and maneuverable and can be parked anywhere! I drive a lot of miles and it is unexpectedly comfortable, even on long trips. Not a huge amount of power (watch out when passing!), but fun to drive. Perfect for toting around 2 large dogs. Had some problems with the power windows wearing out and the exterior portion of the door handles breaking. Other than that, no major maintenance issues (knock on wood). 145,000 miles and counting!
Size, gas mileage, fold down seats in back.
Make replacement parts for power windows separate (so when they break, one doesn't have to purchase the entire motor, housing, etc.)
