they have done that so that its not sold by ebay with thier extortionate fees, someone will contact them directly to see and buy the van.
i put something on ebay to sell, free listing fee's so saved £4.70, item sold paypal charged £5 fee's then ebay charged a following £15 final value fee. so that's nearly £25 for £150.
so i wouldn't want to sell a vehicle on there.
