I came into the Aveo because my full sized truck was guzzling too much gas. I wanted an inexpensive commuter. I ended up with a pretty upscale, (for an Aveo) 4 dr LT and it's much more car than I expected. It's smooth on the highway, and comfortable and has many features you wouldn't normally expect to find in this price range like side airbags. The sound system is nice with the MP3 changer and the steering wheel controls are good too. I went to the dealership just looking, but the price was too good to pass up after I saw how much car I could get for the money.
The interior on the 2007 is nicely upgraded and the sound system is really nice for a car in this class. The handling is very nice.
As most have noted the cupholders feel like an after thought. For a car designated as a commuter is should have a better design. It really needs a better dome light, very dark in the back at night. Lack of Onstar is interesting, but they fixed that in the 09 evidently.
