From what I have been told it is not that a dealer sold their one allocated unit at a higher msrp. It was more to do with the ones that loyal customers ordered and then got a run around from the dealer when the car arrived.
Basically Chrysler wanted this car to draw back more loyal MOPAR fans and they wanted those loyalist who ordered them to get them and tell how great the car is.
What they are doing is looking back to see how many people actually got the car that they ordered. If they did not get the car, they are contacting the customer to find out what happened.
That will not be the sole reason why they may drop a dealer, it may be more to what some others said as consolidating to Chrysler, Jeep, & Dodge into one dealer.
Not all dealerships tried to tack on an extra 5 to 15k to cars that were ordered for a customer. There are some good dealers too that did not do this and will earn more loyal customers.
Those loyal customers are not stupid and backed away not just from the dealer but from Dodge and the Challenger. Now only a few loyalist own the Challenger along with some rich guys with one in a garage and not being driven just to say they have one.
