A mixture - I have brand new from when the relay dropped to below 15k
But normally I buy vans that are about 5 years old - one owner full service and low mileage where poss - this way I feel you get more van for your money, depreciation is less overall and they are still tidy and smart
As with anything employing, don't be to emotional over it should the worst happen, like a prang - that's what's insurance ce is for
