I'd get a cobalt. I belive it's a best kept secret in the market. It has more standard horsepower and gets 25/37MPG for the xfe model. I currently have a 2010 cobalt coupe xfe. All I know is I can outrun my friends 2008 civic with no problem. Mine has small upgrades such USB input and floor mats.
But obviously it's your choice.
Good luck.
