I agree with Steve, I believe that most of these cars would go 100K miles with only corrective maintenance. I guess there are too many people that prove this all the time.
This is why the junk yards are full of cars that didn't get put there by collision with an 18 wheeler. With a well built automobile, constant preventive maintenance including indicated service, inspection and then correction of whatever may fail inspection, will keep a well built automobile running virtually forever. The key is listening and feeling for problems as well as regimental preventive maintenance.
There are so many people that think that a car is worn out at a certain mileage, 100K is a common number, that it's unbelievable to me. There is no reason, that most cars, especially Benz automobiles, can't go multiple hundreds of thousands of miles. I've proven it with more than one.
