2007 Mercedes-Benz S-Class S550 4dr Sedan (5.5L 8cyl 7A)
Best driving, handling, quietest, smoothest MB S class ever. Stereo is superb. COMAND functions simplified, still a learning curve. My car was sent back to dealership twice in first 3 weeks because engine stopped abruptly while on highway. Fuel sensors were defective. This, along with a vibration on the rear deck. Otherwise, car is perfect. Interior finish far better than prior models; engine power rivals my Porsche. Very happy I bought this one, but if you are a stickler for reliability, buy a Lexus instead.
