Which used Mercedes M Class 4x4 should I buy?
M-Classes are now widely available, but avoid Mercedes dealers to find the keenest prices, especially on older models.
If you can, go for a face-lifted model from a 51-plate onwards. Although the car didn't drive much better after these tweaks, the improvements to the materials and layout in the cabin went a long way to answering the criticisms of the original model. With any age of car, the 2.7-litre diesel is the best engine to choose, and preferably with the automatic gearbox. As we've said, the car's chassis is not the greatest, but its limitations are least obvious with the less powerful engines.
