I'm about to do the same upgrade. I currently have my Commemorative Edition SRT-4 for sale. I've got two people coming to look at it this weekend, so hopefully I'll be picking up an SRT-6 in the next couple of weeks. I've wanted an SRT-6 ever since I drove it a the SRT Track Experience. I just figured they were out of my league price wise. After looking around recently I noticed how much they have dropped in price and my mind was made up. It's good to be a dealer, so I'll be picking one up at auctions hopefully for $20-21K for one with little if any mileage. I saw one run the other day at Mannheim Auction with 6 miles on it that sold for $20,700! Hopefully there are still a few still out there when I'm ready.
