Motoring Today currently lists 3 Mercedes-Benz E-Class models available, with prices starting from £17,995, or from £390 per month on a representative finance example. Drawing on national DVSA MOT test data from 46 real UK tests, the E-Class has a pass rate of 69.57%. This figure reflects cars presented for test, not necessarily their lifetime reliability, as pass rates often cluster with vehicle age and maintenance levels rather than the badge itself. The most common reasons for MOT failure in the Mercedes-Benz E-Class are Suspension (25% of failures), Tyres (25%), and 'Other' defects (19%). For anyone considering a used E-Class, these statistics highlight crucial areas to scrutinise. Issues with suspension often indicate worn components like springs, shock absorbers, or bushes, which can affect ride comfort, handling, and safety. Tyres, being a common wear-and-tear item, should be checked for adequate tread depth, correct pressure, and any signs of damage or uneven wear. Before purchase, it's always advisable to arrange an independent inspection, paying particular attention to the suspension system for any noises, leaks, or excessive movement, and thoroughly checking all four tyres. While an MOT pass rate offers a snapshot of vehicle condition at a point in time, a full MOT history, readily available on Motoring Today listings, provides a detailed record of past advisories and failures, offering further insight into a specific car's maintenance journey.
