Hello, Bjorn,
If you search this archive, there is plenty of advice re vans. You can also try here:
http://forums.boards.mpora.com/showthread.php/53904-Van-fit-outs-A-compendiumHiAce: excellent parts availability, reliable, durable.
VW and Mercedes: expensive parts (but there are second-hand and non-genuine importers), make sure there is a local mechanic or shop near you who can work on them.
Hyundai iLoad: a real challenge to Toyo, Mercs and VW and worth giving serious consideration. Get the diesel, manual transmission spec. Good load space and excellent driving characteristics (much better than Toyos, but not the Euros).
Ford Transit: only get the VM model and the later the better. The load space, even on the FWD SWB model, will blow your mind.
Just remember: on front-wheel drive vehicles, if a clutch goes, the whole engine and transmission has to be removed = quite expensive.
Pitfalls: watch out for rust beginning in the load space, the floor and behind plywood wall protectors. Seek advice in the Forum (there???s some excellent advice from a dude named WindmanV

). Have a look at Valvoline Tectyl 506, which dries faster than deodourised fish oil.
Hope this helps.
Flanagaj: the Hiace in the UK was the SBV here and it was deleted from the Oz range in (I think) the early 2000???s, because of poor sales. The current-shape HiAce in Oz has not been taken up in the UK because of engine-emission standards. You can Google for info. Toyo UK are looking to badge-engineer from a Euro manufacturer for their next HiAce (Google again).
