The most I have paid for a van is £995 for my current van, a 1999 Fiesta 1.8 35, bought 4 years ago.
The cheapest was £54 for its predecessor, a 1988 Fiesta Mk2 van.
My current van has had a fair bit spent on it, and just needs a few bits doing to sort it, although it is running well. Bodywise it's in excellent shape, and I have had numerous offers to buy it, but it's a keeper.
The Mk2 lasted 3 years in my ownership and cost pennies to run. I had another Mk2 van prior to that which was in better nick than its successor, and which I would probably still have today had it not been stolen and written off.
