What should I look for in a used Mercedes M Class 4x4?
You may well be a little concerned if you've ever seen survey results for the previous M-Class, especially its bottom-five finish in the 2005 JD Power survey. However, this model is a major improvement on the old car. It certainly feels better built and uses higher-quality materials.
That should at least bring this model more into line with other Mercedes cars. Figures from Warranty Direct show that, if you were to draw up a league table of reliability, Mercedes would put in a respectable mid-table performance, on a par with BMW and Volvo, but well ahead of Land Rover and Jeep.
