This dealership is not far from me. I purchased my first GT350 from them. They have been specializing in a lot of high-end mustangs - various Cobras, Shelbys (Super Snakes), GT350s, GT500s, Cobra Jet drag car, etc. I don't ever recall them offering a GT350R for sale. Their inventory is not that great right now. I came across these "Revenge" mustangs as well, and I am not unimpressed. That is a crazy price tag for that vehicle.
This dealer group also has a new store in Jackson, OH area that specializes in very high-end vehicles - Porsche, Ferarri, Lambo, McLaren, Aston Martin, Mercedes, BMW, etc.
Sooooo all of those go fast parts, but absolutely zero mention of actual parts that help keep the car on track, that is 100% required of the S550?
