I found a boat, its an 89 Sea ray 200BR, with a 4.3L. its in good shape and has a trailer with new tires. It was listed at 4200, but the guy will take 3500. does this seem like a good deal? I missed out on an 88 18ft for 2500 last week and I do not want to miss out on another. It does come with a convertible top and bimini top.
