And a Happy New Year.
I bought mine from Japan and it's nice and rust free, but they are not giving them away these days. E.g.

But you get a good choice (that one's a manual 4x4 for instance - my search was 'Toyota Hiace super'.
Add 32% on for VAT+Duty on the total (van + shipping). You are at Bristol I see though so it's easy to collect
Edited to add:
This is a better price, 2WD auto and has Climate Control, of which I'm rather jealous LOL. No pictures of the underneath however (mine had quite a few so I could see it was rust free) butyou could ask them to take more. Looks fairly tidy.

This is the place I bought mine through, good people to do business with.
The main problem I have with the Hiace is that there's no modern replacement. The compact nature of the space, the Toyota build quality and the sunroofs etc - if they sold them here I'd be tempted to buy/lease a new one - such a shame no modern van does the job.
The Fiat Doblo, SEAT Alhambra and Ford Tourneo are the best I've seen but are still much smaller inside.
