I would still hagle a little make them work for your biz ... dont just ring the bell and take the deal theres no fun in that ... and if you can get the manual then that would be a god sent . those things arent cheap
Make em sweat. Let them know your offers again. If they say no walk away. Wait a week and shoot em your offer again..continue on that path. A friend did that, it took two months for the dealer to cave, but they gave him what he wanted.
