I've had my 2010 Chevy Aveo for 3 years now (I bought it new) and I love it. Yeah, it's not powerful and it's not the most beautiful thing on the road but I don't think it's any uglier than the rest of these new, weird looking vehicles. I like the interior, it's plenty roomy enough, I've done a couple cross country moves with me, my husband and three dogs (and all our stuff). It's super efficient, which is the most important to me. I can't afford $80 - $100 + a week to get around. I can fill up for about $40 and that gets me almost 300 miles. It's never ever given me any problems, except the driver's seat fabric has a rip from wear and tear, I guess. Make sure to change the oil, it'll last.
It's roomy for it's size, and the most efficient car I have ever come across.
I can't really think of any, except a better console area for storage.
