I would offer to tow vehicle from house free, if no dice, then offer a VERY low price
150.00 or so. Always, I say again , always start very low on price
for the back yard boats. the boat is just rotting away anyway, owner probably just keeps it for sentimental value, or the old "I'll get a round to fixing it someday" idea. here in Florida
USA, there are thousands of boats like this on lots, canals back yard. Offer to remove it free the most they can say is NO! you can go on internet
ie. Craigs list e-bay and find as good if not better free or next to nothing. just my thoughts.
