I purchased my Yaris 3 years ago to upgrade from an old, fuel-guzzling Dodge Dakota. In the three years I've owned, there have been no major repairs, no problems, only standard maintenance. My gas mileage has ranged anywhere from 34-40 mpg.
Accessible side cup holders. Spacious interior for size of car. Trunk space. Fuel economy is amazing.
Acceleration is weak. Safety ratings are low, but that's to be expected with such a compact car. Never had an accident with it, so no experience with safety ratings.
