I've had my Yaris for six months now and I still love it. I get over 40 mpg on the highway and mid to high 30s in the city. It doesn't accelerate fast but that isn't what I wanted. This car the best you can get without going hybrid. I got it on a lease but if it lives up to Toyota standards I'll probably buy it out at the end.
Gas economy, cargo space with the rear seats down, more leg room in the back than almost any VW.
More than just the one power outlet, and the one that is there is weird. Everything I plug into it feels loose.
