I've never been able to get one broken in as early as 92,000 miles. My 240D had something like 300,000 miles before I even carried a toolbox. My 300E has just hit 240,000 and I wouldn't be afraid to take off on a multi-thousand mile trip.
It wasn't that long ago when 100,000 miles was par for even a well taken care of car. Now 250,000 is well within reach for most any car if its reasonably well taken care of. For a Benz, that point is far beyond even that 250,000.
