This S350 is smooth powerful and fun to drive. I have 6,000 miles on mine and it's the bast car I have ever owned including other Mercedes, Lexus, and Audi models. Interior is well laid out with all controls within easy access. My car gets 37 MPG on the highway and I am averaging over 31 MPG in mixed city and highway driving. 4 Matic works great in the rain or snow as well. This truly an exceptional ride, but be aware of expensive options as they are way over priced.
Smooth steering, great traction in bad weather, super MPG.
Options are too expensive, navigation system lacks features other manufacturers offer
