Ford is only allotting dealers a limited number of the new Mustangs. If it's a big dealership,they get a few more. Ford also has a habit of saying to the dealers," You want three Mustangs? Well, then you have to take 2 Freestars and a couple of Taurus."(or whatever they have in their surplus/slow sales category).
Why aren't the new 'Stangs selling so well in Ontario? Blame the insurance companies. Example: I have a clean driving record going back many years. For a 6 cylinder Mustang, my rate would go up an additional $ 760. For a GT, it would go up $ 1210!
I've heard of one guy who was ready to plunk down MSRP on a new GT only to find out his insurer wanted almost $ 6000 annually to cover him.
