I agree - if you check something while the seller there, and it is broken (i.e. a stuck stem or seat post), that can aid in your negotiations. For many people, if the bike needs something relatively simple to repair - but they don't know how to do it, or don't want to pay someone to do it, that can bring down the price of the bike considerably.
