My lease on my truck isn't up till August of 2016 so I'll hopefully be able to get in on some nice incentives plus x-plan. With my luck though they'll be announcing the direct injected 5.0 by then and I'll make myself wait it out!
I think it might turn out to be more accurate to compare the difference in prices between 2014 Canadian and US Mustangs and then apply that difference to the 2015 Canadian prices than it would be to just apply a currency conversion rate to the Canadian prices. See if my work below makes sense...
