the best part is that it takes regular gas not premium

I think there is $4500 in delivery allowance on 2011 GT but I'm not sure about V6. Go for an 11 if you can find it and save some money. There isn't alot of margin on a Mustang so if there isn't any delivery allowance on a 2012 (which I don't think there is) the dealer probably won't move much more than a couple grand. There is also $1000 custom car cash probably on both the 11 and 12. If you check out www.ford.ca it will tell you all the current incentives that Ford is offering.

Buying a present year model late in its run always saves you $$$$$$$$$$$$$$$$$
