I bought my 2009 LT sedan Aveo back in May before the cash for clunkers. I love the car for the most part. Mines more of the sport version with a small spoiler, sun roof, leather seats, Alloy rims and a nice deck. I'm just about to hit 9k cause I bought mine with 3k on it. It still running great I like the sedan way more then the hatch back because you get more room. I'm always hitting 30 mpg and on the highway I'm hitting about 34 mpg. Great looking sedan. This was a 2009 Aveo built in 2008.
Sun roof, deck with the aux port for Ipod, rims and the size of the car.
Don't just put an arm rest on the driver side put one for the passengers as well, that way they can be happy with the ride as well.
