Why dont they sell land rovers with trailers any more?
And what has happened to the cooks body works trailers? Are they all sold off or some still in service?
AFM don't actually know what is coming up for auction, what happens is that in the month or so before an auction DDA start delivering them vehicles and trailers that they put into one of the upcoming auctions. Not everything at Minto etc, will be sold at the next auction. e.g. when I picked up B52's last trailer before Christmas they had just been delivered a Haulmark MC4 20 Ton heavy plant trailer. That trailer is not in the current auction.
If you want a Cooks, a friend bid on and won 2 at an earlier auction, one will be surplus to need. If he sells it he was going to ask $2,500, or that's where he would start the bidding on eBay.
