What's my V worth?

[swampbilly 1980]

I've got an '84 V-20, cc-step lift/150 Johnny and a mediocre trailer-dual axle, boat in moderate - good shape when I got it. Most of what was wrong was cosmetic. Paid $2500.00- and I thought that was a good deal. It was useable ...turn the key and go. Had the carbs rebuilt as it sat for a few years on the boat lift.
