Take your time and think it out. If you really love that boat, make an offer. They can only say yes or no.
I don't know how heavy that boat is, but the Nadaguides site should say, if you look up that boat and click on the "Specifications" tab.
The Spectrum I pictured above is very useful. It actually bumped my beloved Princecraft. I never thought I would sell that boat, but I did, a few weeks ago. Kind of sad, but this new boat really does tick all the boxes. It's a little heavier, but not much. It has better seating, more room, a better layout, more protection from the elements and is more family-friendly. The only real negative is carpet that must be kept clean, and it's an older boat.
The big difference betwen our boats is that I got mine almost free, but put many hours rebuilding it. I have about $950 in materials and probably $2k of labor in it, so I'm all-in at about $3,500.
Would I pay $3500 for it as-is, no labor? Heck yeah! I'd probably pay $5,000 as it is now, knowing how solid it is, inside and out.
You are looking at 4X the cost, but also at a very nice boat with good resale value.
If I were in your situation, I would be searching online like a maniac and I would find a deal I felt good about. Then I would go see it in person, and look carefully before pulling the trigger. That way, there are no regrets.
