In general, I don't think of fair prices as 'sticker', you know? I agree with you totally, too. I had someone lowball me for my van, and I flat told him I would take a baseball bat to it myself, before I let it go for *that*!
My daddy is funny about pricing. We looked at Jeeps when I was twenty, and of course their prices were firm. (summertime). I ended up going with something completely different. i at least wanted some free floormats! ;0)
