Everyone knows the Prius is fuel-efficient. That's why we bought it and we haven't been disappointed. Now that gas is in the $2.25 range, I rarely spend more than $15 to fill up, and that will last me more than a week. Using less gas means we're emitting less CO2, and that's more important than anyone seems to realize. Now that it has over 110,000 miles on it, it's still just as efficient. The car was five years old when we bought it, and it's treated us right. We've paid for scheduled maintenance and have not had any breakdowns or malfunctions. The interior is comfortable, even advanced for a car that's now eight years old. It will pair with our devices over Bluetooth or we can play music directly with the audio jack. It also has a great map function, and I love the keyless entry and push-button start.
