Definitely a good idea. When I bought my Evo I drove to Jersey to deal. For them I was “found” business or someone they wouldn’t normally get through their door. I went in with a good trade in and a fair deal in mind. I had excellent credit (got 0%) and being a salesman myself I knew exactly how much they should make off of my trade in and what their hold-back would be. Despite all my knowledge, credit and fair offer I still had to battle but that’s just part of the game.
