This was Merc's first take on the luxury off-roader, and it didn't pull it off with this first-generation car; the M-Class has never had the cachet of the BMW X5 or the Range Rover. Build quality issues dogged the M-Class from new, making it a cheaper used buy than rivals. That makes it tempting, but the Merc can be highly problematic, so be very careful before handing over any cash.

  • Build quality isn't what you'd expect of a Mercedes; on some cars there have been structural build quality problems because of missing spot welds.
  • If you buy a car with the optional rear-mounted spare wheel, check the rear visibility first.
  • Mercedes dealers are expensive and sometimes offer poor service; test your local dealership before buying.
  • The six-speed manual gearbox fitted to the ML270CDI has been known to fail - expensively.
  • The multi-section sliding steel sunroof frequently goes wrong; the motor on one side fails, leading to the whole thing seizing up.
  • Catalytic converters can split, with replacements being very costly.
