I've had this car for just over a year. It's been a great ride. Frankly, it's been perfect. The size is perfect for city driving. The power and ride are excellent on the highway. The build quality rivals the fit and finish of much more expensive cars. The seats are very comfortable. The sound system is excellent. The rear seats and hatchback make this car very practical. As for fuel mileage, I'm happy. Having an AT diminishes the mpg (I'm getting as low as 33 and as much as 38), but it's still better than most. The turbo deisel runs smooth, quiet, and has lots of torque. If your looking at buying a small car, you can't go wrong with this one.
It's all good... comfortable, fun to drive, tight build, nice sound system, good mileage.
If I have to say something... folding down the rear seats can be a bit of a hassle, but I've only done that once since I've had it.
