High mileage diesel vans can represent good value for money, but the price must reflect the condition. You also have to make some important checks beforehand. For example, it must have a full service history. Personally, I'd look for oil and filter changes at every 10k miles or every 12 months (whichever came first). If the van's documents don't show this then I'd avoid as it won't bode well for the remaining life of the engine.
