I bought my Cobalt a year ago and still LOVE it! I had always driven v8's so was a little concerned about going to a 4 cyl, but was very surprised with how much power it actually has. It also handles very well. I live on back country roads and it takes curves wonderfully. Plenty of trunk space makes traveling easy. Also has a GREAT stereo system. The remote start is also great for warming up or cooling down the interior before getting. The back seat is a little tight though.
Remote start, sunroof, large trunk, stereo system and cruise control.
Ability to lock power windows, more room in the back seat.
