What on earth are you rambling about?
I had a brand new '56 Passat for thee years and clocked up 90k without an issue.
I liked it, so needing a run around for a few months I bought myself a 7 yr old one. I have no idea if this one will develop any issues, but at 126k it seems to be running well.
On my experience of owning a Passat, I recommended one to the OP. With £9k to play with, he'll be going nowhere near 7 yr old 100k+ one.
Are you always this hard work?
