I bought my Hellcat from Kranz Dodge outside of Wichita. I dealt directly with the owner and we worked out my trade value and price of the car before I traveled there from Colorado. Another dealer I've heard good things about is Landmark Dodge in Independence. They were pretty aggressive with their Hellcat pricing when there were still markups at most places. I forget his last name, but they had a sales guy who used to post on the Hellcat forum by the name of Dennis who seemed like a pretty straight shooter. I stopped by and talked to him when I was home in Kansas City and in the market.
Oh - I was looking at Landmark but their listing said something that seemed to indicate the shipping of the car to the dealership was extra, which should really be part of MSRP, but I may give them another look. Thanks!
