Sounds like you already have it pretty well figured out. Find out from your local dealer what he requires as far as identification from the out of state seller, and what he plans to charge you for a transfer fee; anything from $25 to $100 nowadays.

As far as negotiating with a seller, it works just like it does face to face. Know what the value of what you're buying is and dicker from that. Ask for a 3 day return privilege, and don't deal with anyone who won't go along with that...Geo
