2010-reg Diesel, Owner for 1 to 3 years

Whilst the car has not let me down there are rattles in the cabin, particularly from the drivers side window, the centre of the fascia and the front passenger seat. there is also a delay in acceleration which mercedes are unable to fix and I consider a safety issue. I have test driven several others and they all have this problem. 25mpg at worst 45mpg at best. only my low annual mileage and the comparitive high cost of diesel make it not worth running a diesel car.

It has fantastic, quite individual looks. Incredible balance of performance (it is the "Grand Edition" with a power upgrade) and economy. The ride would challenge Bentley for its smoothness and cathedral like silence. At £55000 it was not cheap but after several months of test driving various makes and models thyere was nothing that ticked more boxes than the CLS Grand Edition.

A stylish wow factor looking car. Brilliant diesel engine with reasonable fuel economy for size of car. Always gives feel good factor when in the driving seat and also for head turning satisfaction.
Have only experienced minor problems which mercedes have been more than willing to sort out with minimum fuss and excellent service. I would strongly recommend this car!!
