Ordering should carry a better deal than an in stock boat if done right.
These are all great points, and it's great to get advice from boaters that are more seasoned! I definitely lean more toward ordering rather than settling for something that's not exactly what we want. I do hope that ordering doesn't remove too much of the bargaining power though. It's hard to keep that last point in mind - that the dealer wants to sell you a boat more than you want to buy one! Great wisdom there!
Just be honest with the dealer and tell them you have no interest at all in their stock boat.
My dealer had an R5 in stock that I could have bought cheap. He would have loved to move that boat, it I told him that it was definitely out, with no chance to sell it to me.
Now, his focus changed from selling his boat, to getting a sale.
Negotiate it at the lowest point of foot traffic in their doors.
