In reply to daWalt:
Try the VWT4 forum.
Their classifieds include T4 and T5 vans.
But you won't find many cheap vans.
Plenty of nicely converted but expensive vans or cheap projects.
You need to move away from VW if you want a reasonably priced van.
It's reached the point where T4s are as expensive as early T5s.
I sold my home conversion T4, 1997, 140,000 miles last month for close to £4000.
And I thought I was asking a low price for a quick sale.
Good luck with your search.
