Looking at a 2010
 

First off, I'm sorry if I'm posting in the wrong place, I'm really confused as to how I even got here. xD I'm looking at a 2010 Chevy Cobalt LT2 Sedan, it has about 61k on it and I'd really like some input on what people think about this model year? Is it reliable? I'm wanting to buy a car that will last me for 5 years+, if not longer... What's the max mileage these things can get if I were to keep up on the regular maintenance? Super scary time, I'm 19 and this is my first serious car buying experience - my first two cars I bought off of Craigslist and they turned out to be duds. :( Like I said, I'm sorry if I've posted in the wrong place and I would gladly move my post elsewhere if ya'll would like me to. :)

if you keep it maintained, you will have no problems

That battery will die in 2015. Cobalts batteries last five years.
As for your other questions, I don't know. The best thing to do, would be to take it to a mechanic, and pay him to look it over.
