Had mine for 6 months, and it's a great car. Easy to drive, and sits high enough in the interior so I don't feel like I'm driving a small car. I've taken it on one long distance trip, and it was very comfortable for 4 people. I'm averaging about 33 MPG commuting in the city. Lots of fun to drive, and parking is a breeze. People constantly stop to check it out, and I've been surprised at the amount of cargo it can hold with the fold-down seats. I traded in my Camry for the Yaris, and don't regret it for a second. It's simply a fun little car!
Several people hate the cup holders, but I love them. The placement in front of the air vents actually keeps my drink cool! Might be a problem for coffee, though. The gas mileage and seat height are great, absorbs road bumps with ease. Lots of storage for such a small car.
