Anybody got any lemon law experience?

I've got a car that looks like it might be bought back by Hyundai.  I know that state laws vary on this, but wondered if anyone knows how this sort of thing works in a general way?

For instance, how do they determine the buyback price of the car?  I am hoping that they do not buy back at a trade in value... that it more closely approaches a retail value.  I have no clue what to expect, or if there is room for negotiation. 

Any guidance?
