The MERCEDES-BENZ M CLASS is a premium, five-door SUV, offering a higher driving position and more space than a typical family hatchback. In the UK used market, it sits among established luxury 4x4s, appealing to buyers who want comfort, presence and practical room for passengers and luggage. It is larger and more upmarket than many mainstream SUV rivals. It suits families, regular travellers and drivers who value a comfortable long-distance car, while its generous cabin and useful load space also work well for holidays and everyday errands. mycarcheck.com has recorded 37,725 M CLASS look-ups covering 15,652 different VINs, a substantial sample. Across those checks, the average private-sale valuation is £7,500, with average recorded mileage of 110,000 miles and around four previous keepers. Check service history and condition carefully, especially at higher mileages. The M CLASS stands out for its solid, refined feel, but luxury-SUV running costs may exceed mainstream rivals.
