Hi, I just took delivery of blue '07 GT/CS. I probably paid too much for it, but really don't care. The previous owner lowered it, put on a Pypes mid muffler kit with an off road X. The dealership had to install cats to sell it, but they were smart and put in some high flow units. There are numerous cosmetic items as well, like rear and side window louvers, billet grills, the rear wing and a portion of the hood were painted black and a few things inside. It was all very tasteful and I have no plans of getting rid of any of it. This is probably my 6th mustang, but it is the first S197.
