I split this between passenger use autos and work vehicles.
ON a a passenger auto its typically between 150-250K miles where repairs start to cost more than the vehicle, and you get cascade failures.
On a work vehicle I have no upper limit on a well maintained machine like a 7.3 f250, or properly rebuilt loved and cared for asset.
Ive been in 20 year half million mile farm trucks Id trust more than some beaten neglected 5 year old trucks with 60K
There is no reason a properly maintained vehicle cannot go forever.
