I have found from talking to a lot of Charger R/T and SRT owners that you should be willing to travel to get the best deal.

When the 2009 models come out, I will check out my local Dodge dealers in the Philadelphia/southern New Jersey/Delaware area. If they are unreasonably high (expected), I will contact dealers out-of-state up to 500 miles away who sell large numbers of SRTs for the best price.

I checked with the SRT engineers during one of the chat sessions and they advised me that there would be no problem driving a new 6.1 SRT a great distance, as long as you stay away from wide open throttle.
