Mercedes-Benz S-Class Saloon S350L CDI BlueEFF. 4dr

For The 350 CDI diesel provides strong performance yet is refined and reasonably frugal. It's our favourite engine in the range. Long-wheelbase models have palatial space for rear-seat passengers.

Against This long-wheelbase version won't appeal to keen drivers as much as the short-wheelbase one. Even with the diesel engine, the S-Class isn’t exactly cheap to run.

What Car? says

5 out of 5 stars

You pay a lot for a few more inches of rear legroom. It might be worth it if you're a chauffeur, but if you'll be driving, stick to the short-wheelbase model.

Buyer's notes

Target Price team says:

You could certainly argue that, pound for pound, the S-Class is the best car in the world. Whatever you want from a luxury car, the big Merc does it - and does it very well.

Despite the fact that there is a wide range of petrol engines to choose from, the best S is the 350CDI, with a diesel engine that's flexible, frugal and very refined. Unless you'll be the back-seat passenger, don't bother with much more expensive long-wheelbase model, though.

On top of the three-year unlimited-mileage warranty, Mercedes cars also come with the Mobilo breakdown assistance package that provides you with assistance on the road for up to 30 years in more than 30 European countries. Different benefits apply, depending on what the problem is, and full details are available from the Mercedes Customer Assistance Centre.
