I know it might not be that much of a discount but why not try the car auctions. Dad was saying that one of the people he was talking to bought an ex shell tanker, it came with a brand new paint job, re built motor and it only cost them 66000. I think it was a 12 tonner. Dad bought his through a truck yard, it was an 03 model, 50000k and it cost him 67000. Just goes to show that hte auctions might be good after all?
