I think there is (or used to be) a sticky in the gen 2 forum about the lowest price on a new gen2 busa in given regions of the state...
I personally negotiated 10,800 + tt&l here in the southwest... I went to the stickied thread I mentioned, called up the dealer in ohio that was selling em for 10,400, asked if they were still offering that price, then took that price and called every dealer in my state. I told them that an out of state dealer offered 10,400, but if given the right price, I would stay in state. 10.8 was the best, but I also saw plenty of other dealers offer a lower price.
They also gave me ~half off on a new helmet, too.
