I've owned the following , LS400, (2) Q45's Qx4, 528e, Caddy's and Lincolns. This my 7th S class I'm very happy . it gets plenty of looks and so far in 8 months I put 15k miles on the car. Now I'm starting to see little expensive things like transmission seals, control arms, and when we very cold days like below 28 degrees the pump for the suspension stop working.luv the sound system, but it sways a little at high speeds. I've never driven any other car @ 130 mph. Gas mileage stinks in the city. Nevertheless I plan to buy another one when I can.
Sound system, super ride, looks, fun to drive, comfort, space, and the power front seat cushion, thats really why I bought the car.
Better seals like the old Mercedes so the transmission dosen't leak with such low mileage, better cushion in the seats.
