If it's tidy body wise are you a defo fix any mechanical probs then go for it,
A nice shiny van is a 'nice to have' but not a 'must have' I use ldv vans because they are cheap to buy reliable and do the job well - no street cred no 100 mph trips up the motorway no nothing but as I usually save 1,500 to 2k to an equivivant tranny or similar who cares.
In the early stages of building every penny should be justified before spending otherwise you'll have a flash van, but no decent equipment to work with...
