Miledge isn't so much of a problem with newer engines, providing they have been serviced regular.
Its not uncommon to find Vags and Bmw's with 250k+ and still run perfectly!
Obviously things like bushes and other things wear out but I would happily buy a car with 150k on the clock.

Its not like the old days when 100k was time for the scrappy.

You can buy some cracking motors at rock bottom prices if you don't mind 100k+ on the clock
