Don't confuse dealer delays with production delays. Do you have a VIN? How long did it take to actually get that VIN?
Dealerships are on an order rotation. Last I knew (model year 2010) it was 6 weeks. So in other words, the dealer could take your money day 1 and not actually place the order with Ford for over a month.
And even then, the dealer doesn't have unlimited slots. Most get 2. So if you're order #3, you might not get submitted until the following cycle, and so on.
No dealer will yell you that of course. They'll take your order and keep you posted, of course. The only real way to know you're past the dealership crap is that VIN. If you don't have one, Ford doesn't know you exist.
I'm order #1 of 2 at my dealer, no money down, he is a personal friend and i have a copy of the order placed and Ford customer service / SVT program have both confirmed it was placed Sep 2nd, so there is no answer for the bs I'm dealing with.
