Mmmmm, I think if you can find something with solid bones with the intention of doing a complete refurb on it, you can accomplish a few things. First, if doing the work yourself, I think it will be hard to spend so much on a complete total refurb that you will have spent as much as a new boat might cost. Second, a well thought out total refurb. (not a rush job) will leave you with a totally custom boat, that will be your favorite floor plan, done in your favorite materials and colors. On our project, which included new anything not aluminum, including some pretty expensive padded vinyl floor covering and the price of our "in need of total major service" 90hp Honda, was about 6500. After selling the 40hp Johnson that was on it, we're actually into the refurb for 1500 less than that....
In the market area I'm in (SE Mich) that's about what a solid set of bones with decent power might be worth. If you were to buy one like that, then spend 6500 on it fixing it up, you'd STILL be at only about 25 to 30% of what a new boat might cost.
Bottom line, I'm guessing you'll be into yours at what most would consider to be a great deal compared to a new boat.
