The best advice I've received is to wait it out one year after the initial launch. By then, all the madness will have started to die down and you will be more apt to get your Challenger at MSRP or below.

I do have a question though - how long would it take (roughly) from the time you order one at the dealership until you physically take delivery? Anyone care to gaze into their crystal ball and help The Beener out here?
