I think we should clarify the difference between a discount and a rebate.
Rebates come from Ford, and run typically on a month to month basis. They are also zip code restricted here in the US.
Discounts come from the dealer, how much they take off the MSRP of the vehicle.
You can get a discount on a 2014 similar to a 2013 but the rebate comes from Ford and cannot get the same rebate on a 14 as a 13.
