The best advice I've ever had about buying
stuff was 'you make money
when you buy not when you sell'. I'm not advocating you can make money buying
a boat but what this gent meant was don't get emotional and don't pay too much.
We made a couple of low ball offers that were rejected and finally ended up getting a very well maintained and equipped Liberty 458. Good boats that sell quick seemed to go for about 15% below asking. We looked at over 125. Occasionally you hear about the deal of the century but it's rare.
However boats that have been on the market for a while probably don't have a good match between asking price
and market demand. Make an offer you think is fair value for you.
