 Just traded in the 2006 Mercedes ML-350 with 116,000 miles on it. Worst car ever. Reliability was terrible. Resell is horrible. Basic maintenance is extremely expensive. Had battery troubles, alternator troubles, and electronic troubles. Horrible design. Electrical boards are under the seats, so you can't get anything wet. One time the wipers, alarm and locks went off just because the battery was dying AGAIN. Automatic liftgate never worked. Sick and tired of Mercedes and will never buy again. Traded it in for a 2013 Acura RDX.
