I've only had my car for about a month and so far it's pretty nice to have. As with others my gas mileage is only about 22mpg with the auto, but I drive kinda crazy. Other than that the car is great. The driving position is great. I feel like I'm in a mini SUV. The radio could go a little louder. It has lots of ammenities though it's a little underpowered. All in all it's a great car for the money. I think the Aveo is like an inexpensive Beetle, it's colorful, cute, shapley, and it has personality!
Comfort(seat height) Cost! size! makes it very easy to handle, tight turning circle
Rear reading/entry light, better speakers, switch gas tank to other side
