Gulf Stream FORD E-450 Super Duty B Touring Cruiser

I would like to buy used 2005 model "Gulf Stream FORD E-450 Super Duty B Touring Cruiser" RV at Highway Caravans (http://www.highwaycaravansmonmouthshire.co.uk) and also I did specific research on used RV's.. After the long negotiation with the seller, he ready to sell his RV at £33,500. Now my question is "Does the price of the vehicle is Right?"
