I've found this car trustworthy and free from unexpected maintenance. Not recomended for heavy highway driving as wind has effect on car. After 125,000 miles motor is very sound and doesn't burn oil. The interior is roomy and can hold 4 adults with leg room and headroom, or three bales of hay and two adults. I've enjoyed the smallness of the car as parking and turning around is very simple and quick, especially in downtown areas.
Soundness of engine. Boxy style that holds bulky items. Fuel mileage. Easy in and out with large doors. Ease of parking in crowded or busy street.
I would suggest that the brakes be larger to better handle a full load. I would also consider bigger tires to increase tire availability and selection.
