My daughter bought a 2007 Yaris and I fell in love with her car. I would have bought one much earlier, but they didn't come with a cruise control. Finally, the liftback came with a cruise control and I bought one. The ride is great. I drive from Indy to Chicago every week and have gotten 34 MPG in mixed driving. This is a fun car to drive and has a really smooth ride. It isn't a Lexus so you have some tradeoff, but overall, great value for the money and since it is a Toyota, I know it will last a long, long time!
Turning. It is so small it can turn around in very tight spaces. Large cabin for such a small car.
Heated side power mirrors. It has power mirrors, but they aren't heated. Navigation and bluetooth would also be nice options. Finally, Toyota sells the Yaris in Europe with a digital speedometer and tach. That would have been a nice option and I would have paid more for it!
