I think there is a difference between the GT500 ADM and the Challenger SRT8s. The GT500's were supposed to be a two year run only. They only came with the 6 speed manual and 500 HP Engine. The 08 SRT8's are autos and have no stated end date of production. No doubt some dealers will try to gouge their customers, but the savvy buyer knows that more options and plenty of supply are just around the corner. That wasn't true when the first GT500's were sold.
