SLK 250d For Sale My wife has had this car for 6 years and loves it, unfortunately her arthritic knees struggle with the sporty seating position and it's time to move on as retirement approaches. The car is in great condition, the only bit a new owner might want to do is get the wheels tidied up as the wheel paint is in need of attention. This car is surprisingly quick, looks amazing and the automatic roof retracts faultlessly. It will do 60mpg on a long run, we get about 50mpg around rural Norfolk. Built in Mercedes SatNav system. Serviced every year, it has always worked with no issues for all.
