Having bought a 2005 ML500 (W164) 2 weeks ago with no idea what I was doing and verrrry worried I might have just thrown a wad of cash away (no FSH, very little accompanying paperwork and no mechanic check before purchasing it) I've got to say I am impressed. The car has got 110k on the clock and I've put an additional 1k on it over the last 2 weeks. Today I drove 270 miles, mostly underwater and the only thing of note was 2 brief flickerings of the exclamation mark within a couple of miles. Best I can work out upon return and investigating was probably momentary loss of traction. My home town (Hayle, Cornwall) had flooded during the day and I was driving into that storm from about Bristol as it headed up country - probably worst weather I've ever driven in - felt totally planted and those auto wipers, how useful are they?? - coming up behind trucks creating curtains of water to get through - no having to worry about increasing wiper speed - off it goes!!
