I have enjoyed the past 18 months driving, as this car is very comfortable, quiet (rattle free) smooth and relaxing.
The car performs well after about 1500 rpm (before that it is VERY sluggish) that's when the turbo kicks in.
The acceleration from 60 to 'way over the national speed limit' is amazing for such a heavy luxury car. In Germany I have flown from 90 to 125mph in no time. For a diesel slugger at 100 mph it's very quiet, almost too quiet - too easy to speed in the UK.
The C Class has room up front, but is a little cramped in the back when seating four good size adult men, and five is really pushing it.
Despite what people told me, you do get a lot of extras as standard. The dash and steering wheel controls are easy to locate and use.
I suppose the nicest thing about the Mercedes C Class (as with all Mercedes I guess) is that you can drive for two, three of four hours non-stop then get out of the car without having to do a ten minute workout to loosen up again.
The only major problem I have had with this car is that it has been an accident magnet! Two very nice chaps over the last year have decided that the rear of my car is a great cushion to help them stop! Thanks guys!
Service intervals depend on driving styles, but I have only had one so far at 15,500 miles. This, along with 45 miles per gallon average, makes it a very cost efficient luxury car.
