Ordered this vehicle in January and did not get delivery until May. This is the only thing that disappointed about Mercedes. After almost 6 months and just over 10000 miles, I have found very few shortcomings and many pleasant surprises. The most pleasant has be fuel efficiency. Overall combined mileage is right at 27 MPG. Trips up and down the east coast this summer registered almost 30 MPG, both better than the ratings on the sticker. Solid construction, quiet operation, real luxury feel, terrific acceleration and very comfortable seats among the most pleasing characteristics. Only disappointment so far is iPod integration bug which MB has promised to fix. Highly recommended.
