We bought this car as a commuter as my husband drives 80 miles round trip daily. We have almost 34,000 miles on it and get 43-44 mpg on the highway consistently, driving at 65 mph. This car is fun to drive, corners nicely, accelerates quickly, and is amazingly quiet for a small car. I was a little antsy about safety in such a small car, until my husband hit a deer the other night at 55 mph and sustained no damage to the frame or engine compartment, nor to himself I am happy to say! We haven't experienced any problems at all with our Yaris, and plan to keep this car for a long time to come.
Reliability, safety, economy.
It was bought as a bare-bones economy car, and does the job just fine. I do wish though that the cup holders would accommodate the larger insulated cups.
