Just finished a 2,000 mile trip in our newly acquired 07. We drove it from Illinois to Oklahoma City, a trip that had us passing over interstate highways at 75 MPH and rolling through the backroads in Oklahoma. This amazing beast transport the passengers with a feeling of swift, solid sure footedness and capability. The engine is ferocious- at 100 MOH it is barely breathing hard. At more down to earth levels of speed it gets over 27 MPG. That's right, we saw 27.8 MPG indicated and our math upon fillup confirmed the number. The seats are nothing short of nirvana in terms of features and adjustability. The Sat Nav works well and Sirius Radio is a wonder. The SL 550 is simply word class.
Engine, handling, collapsible top, transmission, stereo, Sat Nav, Bose stereo, the beautiful sweeping lines of the vehicle, the best seats ever designed and the exhaust note.
