Just an update on this. My boy found a nice 7.5 1.5 driver at his local main dealer. He drove home in it yesterday after collecting it on Wednesday. Being a bit of a home mechanic, I gave it the once over. I was shocked!
This is an approved used car with just over 40k miles on the clock.
Both front tyres are worn on the inside edges and need replacing, the rear brake pads have only 2mm left and all four shocks are leaking oil!
On doing a few more checks ( we should have done this before, I know) mot history check revealed all these were pointed out at the last mot a few weeks ago, presumably done by VW themselves.
It's going back on Tuesday.
