I bought my ML430 in 04 with 22K miles and some remaining factory warranty. I have had some minor issues but for the most part it has been rock solid. It has used 3 sets of brake pads and a set of rotors over 90K miles. I did have a leak from the power steering pump that required service. The only issue now is that the interior is beginning to show its age. I use this car to tow a race car trailer long distances, it could use a but more power. The Nav system is very dated now but still works OK but there are no data updates anymore. Back seat fold-down system is just plain dumb. Like everybody the glue from the door insulation melts onto the windows on hot days. I still love this car!
