you would be in the mid 60's for trade.. i would say your car and 25K would be in the ballpark of what it would cost you... almost 30 for black edition
+1No. Keep the 2010. There is not enough improvements in the 2012 to warrant the price difference.
THIS.My 2cents: no. U can make ur 2010 perform better then a '12 for less then 5k when it comes to power. The cars are just to similar, Id wait for a more substantial model redesign then just a mid cycle freshening w 99% the same hardware.
