My 1998 ML320 so far has 125,000 miles on it, as of last week. Up until now there has only been one large mechanical problem (involving the transmission I believe), which was fixed under warranty. There are currently several smaller issues which I don't find too pressing. All things considered, it is doing well for 125,000 miles, at least in my opinion. I feel that it will be good for at least another 125,000, which is good because I sure can't trade it in for much at all
I did ask the dealer last time I was in for service how well MLs were holding up after 100,000 miles. He couldn't give me a good answer because I guess most are not quite there yet, so they really don't have a good idea. Anyone have some really serious miles on one of these??
