Question is; when I talked to Neil with the tour group he said they the "company that is handling the retail centers and marshalling centers is an established company that has their own transport group".I wonder if the Adesa Transport in this link is the one they are talking about
So the Adesa you found is trucking, but I don't see where they have the back end to handle the retail part.
Did you look at the two maps I posted? They are almost identical for having centers for handling the marshalling centers.
Perhaps it's time to contact EM and ask them; anybody?
