What sort of mileage are the cr diesel engines capable of ?

I picked up a 2013 octavia estate cr140 in February this year with 257k on the clock, it's just ticked over 267k and running like a dream. Aslong as its been serviced when it should theres no reason why they can't do 3/4/500k 

There was a 170 engined Superb on Ebay a few months back that had been a taxi all it's life that had 642k on it I think.
