Ward, I think what I am trying to say (in Dwight'ish)((what we are trying to say)) is every deal(interaction) at a stealership is different. The purchase of a motorsickle is different than going there and ogling at the lady sales staff or buying service parts. The mechanics may be totally different than the sales staff. The parts counter dudes and dudettes may be different than the sales demons. Each time you go there your interaction will be different. Live to live with the BS and go there for what you want, knowing what you want to pay for it (fair price after all) and if you get BS let it slide. After all they are your local supply. Appear to kiss grits but miss the toilet when you relive yourself.
Regarding trying to negotiate a deal, tell them flat out no on those other charges. If they don't want to sell you a BIKE then so be it. But don't toss them out for buying other stuff.
My gosh am I really writing this? After all, I have zero compassion for any of my local dealers. At all. however, I do use their bathroom from time to time.
