You should be getting a lot better than 2.5k off for a '12. They are giving away the 12's now. Check in before the end of the year and look for at least 8k off the sticker. I'm serious.
As far as the short throw. A big yessssss. I traded a 2010 in on a 2012 with the short throw and it is light years better.
Not even close sspolo. I was always going from 2nd to 5th with the regular shifter. Have never mised a shift with the short throw.
I feel it only fair to warn you, I have a black belt in CAPS LOCK.
