Cheers guys, you've been really helpful.
I'll have a look at a Fiat Scudo.
What sort of mileage should I be looking at, realistically, with a budget of £5K (though I can go to £6K at a push, but would rather not)?
70,000 miles max? Or doesn't mileage matter that much? I see some fairly new vans with really quite high mileage, so I guess most of these would be motorway miles, so is mileage a big factor?
