I know that this is a strange question on a car message board, but there are some intelligent people here. I am trying to find what a reasonable offer would be on a new Cat D6N cabin air dozer. I cant find anywhere online that states the dealer cost or invoice. Is there anyone on this board that deals in heavy eqipment or can find out? We have bought several other pieces of equipment from a local dealer, and feel like the price they want is still too high. We have purchased two other dozers, and an excavator. We feel like we have a relationship with this dealer and would like to continue to stay with Cat. If this doesnt work out we may have to purchase a John Deere 750J. Any help is appreciated.
