Like I said in another post I have found a deal on a 14' v hull w/ trailer.  I am going to look at this boat in the next few days and if its everything he is making it out to be it will be coming home with me.  My question is he told me he was asking $400 but will work with me on it which to me is the same as best offer.  So how do I go about giving this guy an offer thats 1) Still acceptable 2) And also keep him from feeling like I am trying to low ball him.  THanks

Unless the boat leaks like a siv and the trailer is completely rusted out with spun out bearings, the $400 he's offering is fairly reasonable.  Look at it this way, at a $400 asking price you don't exactly have tons of room to insult him.  Throw $275 out there, see how he feels about it and go from there.  Just make sure you've got cash in hand.  That always helps.
