According to the dealer search on the Chrysler website, there is a number of 2005 SRT-6 Coupes available in the Florida market. The dealer search really sucks because it shows all dealers sorted by distance from your location, but if you go through 1-by-1, you can find the SRT-6's. The website indicated they are offering $5,000 cash allowance on the SRT-6's.
I ran a quick search for San Francisco area and found 2 at:
