An SClass drivetrain costs a small fortune to maintain. In general, people who purchase a used S class are wanting the status at steep depreciation prices, and as a rule arent willing to pay the price of routine maintenance.<p>I see both sides of the argument. Buying a good used car for cash is probably a better investment financially. I personally don&#x27;t trust the secondary car market to be honest with me that a car has been taken care of properly. Maintenance records can be and are faked. I generally don&#x27;t mind paying more to have a newer and usually more reliable car with a warranty. I do usually drive them until they&#x27;re paid off plus some time span, but in general its not very long, 1-2 years max.
