Find another dealer outside your area that has realistic pricing...20k over list, they have got to be kidding with the current state of Chrysler and the market place!!...I hope those dealers go out of business. There is a bright side to the Dodge dealers putting unrealistic markups on new Challengers...it will help to sell more Camaros (if Chevy dealers don't follow the Dodge dealers example).
Bottomline is that your Challenger will be worth x amount of dollars in the resale market whether you pay below list, list or over list pricing...and now you can't even justify paying over list by saying you want to be the first with a new Challenger...(I've had mine for almost a year and still find myself to be the only one within miles that has a Challenger)
For less than 20k you could travel across country, find a good buy, and enjoy a nice cross-country drive home in your new Challenger (just beware of any bulldozers along the way).
*Just say NO to dealer markups!*
