Pros: What do you like about your 2006 Chevrolet Aveo? It was cheap.
Cons: How would you improve your 2006 Chevrolet Aveo? Better suspension. Better fuel pump. Better bearings in wheels. Adjustable headlights (you can't aim them). Limited slip differential (let's just say it isn't great in the snow). Better throttle position sensor. Better dealers - half the people that have alignment issues are told by a dealer that it has bent rims (really? muffler bearings are probably shot too).
2006 Chevrolet Aveo Review: It's cheap, basic transportation. If you own one, sorry. If you are going to buy one - buy some tools and a good shop manual, you are gonna need it.
