I glanced at a few of the posts on here..
Perhaps the underlying problem with your attempt to purchase a Mustang had to do with the
dealerships and not
FORD??
There is a dealership that is ten miles from my house.. I would NEVER buy a car from them. Complete shysters..irresponsible business practices... markups on all 'specialty' Mustangs (they let a few Shelby GTs bake in the sun for over a year because they kept the mark-ups).
With that said, I drive to Orange/Riverside/San Diego county dealerships to buy/look at cars... Furthermore, if I get a bad vibe from an a**hole salesman, I will find another..
Don't get me wrong... I like your car.. but I feel that the buyer has to take responsibility in getting the best deal.. it's all about how you negotiate. If you walked out on multiple occasions, and they still didn't accept your offer, or give you more for your trade, than yeah, there is a high enough demand for the new Mustangs that they don't need to sell them for bottom dollar.
I would totally drive the Challenger... And a Camaro... but I would still have some sort of hindsight that I could have had a Mustang..
