If you know the seller and how well it was taken care of, I'd say somewhere between the 5,500-6,500. Remember, it is an 18 year old boat. See if he has any paperwork from repairs, etc. An 18 year old Alpha drive may be tired. I know this : those boats flew. We had an '85 200 Sport with the 350/260 hp. What a blast. Good luck with your decision.
