Probably, but not because a M-B or even a diesel. I have only stopped driving a few vehicles in my 43 yrs of driving - Honda motorcycle (impractical), 1969 Dodge Dart (stolen), 1982 Chevy S-10 (bought new but POS from day 1), and 1982 Dodge Aries (head gasket, a bad decade for gassers). All current vehicles are >200K miles, w/ 1985 300D likely highest at 380K mi (replaced engine). Several had failed odometers or switched clusters, so not sure.
