Buying a V20

Ok.....I need some help.....

I found a 1976 V20 with a 2001 Yamaha Engine.....Engine is in excellent shape. Can't say the same for the boat.

There a couple soft spots around the floor and it only comes with one fuel tank. The previous owner also says he doesn't like to walk on the bow. Also they step ladder is coming apart.

Are these easy fixes? If I could pick the boat 3 to 4 grand would it be worth the trouble?

Thanks for your input
