How long should a ford escape last for mileage?

How long should a ford escape last for mileage? - 1

If well taken care of, 300,000+

How long is a piece of string I wouldn't expect much more than 150 thousand K's out of a alot of the new ford rubbish I see

Much depends on its treatment .manner of driving.terrain.servicing etc. Design life is at least 150K so treated sensibly and barring no unfortunate issues such as component failures. One can expect decent mileage for the average model.

You don't say what year model it is, but if it's a 1.6l ecoboost, don't look for it to last long.
