Thanks for the advice guys. All really what I expected.
Had a look at the van today. A very tidy motor with a full vw service history. Obviously a few age related things but all fixable.
That said, something just niggled me with it having the 204,000 miles on the DSG gearbox which from all that I've read do well to reach 200,000 miles. It was also the Startline trim and not the Highline as advertised.
It will however undoubtedly be the ideal van for someone
