Some people don't want to buy used, I understand, if you want the new Grady don't let the sales department get in your way.
Some could care less about the price you posted and just write out the check, that's what every salesman dreams of for every customer who walks thru the door, but doesn't mean it has to apply to you, it doesn't to me for sure.
I would suspect for Grady boats, it is more common to find more blank check customers than other brands. It was only a few years ago where the best deal you could get on a Grady this time of year (with no leftovers) is the dealer giving you the next year model while holding the same year price, and if you don't like it, don't let the door hit you in the tush on the way out. Then a big smile and have a nice day is added.
If you don't know how to negotiate in these "buyers market" times I also understand, it's been a very long time since it was last this way. So take advantage of it while it's here. I wish I was in the market to buy now.
You can become more of an "educated consumer" by shopping around among other brands too, and other Grady dealers - go to any Grady dealer you want and to any other state, and don't feel bad about saying where you are from. Remember, if no boats are sold, no food on the table. Not to mention electric bills, mortages, real estate taxes, whatever.
Then when you walk in the door, you will know how to get what you want at your price as long as reasonable, if price matters to you, irrespective of what comes out of the salesman's mouth.
You can also ask to see the manager and ask for another salesman, just say it wasn't a good match. This will also indicate you are one step up being serious.
I would suggest you visit the boat shows in your area, not first day, but last day, and talk turkey. They dont want to haul all those unsold boats back to the dealer lot, they have to go.
Like I wrote, my advise is only for people who are not blank check types, not that there is anything wrong with that. To each their own.
