What model? An SRT, R/T or SE? SRTs are limited and you may have a longer wait, especially for a 6-speed.

If you are buying in January, I would recommend that you find one off a dealer's lot. Sales will be light after Christmas, in the dead of winter, and you may get a great deal. Many dealers already have over-crowded lots. In Cherry Hill, NJ (9 miles east of Phila.), for example,a dealer has 27 Challengers on his lot! Also, check cars.com.
