I wouldn't assume there is much room to play with when new, other than the promos the manufacturer runs. I see a few left overs from the previous years pop up for a couple grand off here and there. No idea what the actual markup would be. Given that you are looking at their pricier/larger boats, dig in hard at $5K off and see what comes of it?
One thing with Legend boats, they advertise nice packages at reasonable prices that kinda jump off the page, until you see what the entry level power is. An 18 Foot fish and ski for $31K? Sweet!!! Oh wait, that comes with a 50hp motor, please add $4K for the 90HP upgrade.
