Allied's are great boats. Have it surveyed by a good surveyor and negotiate the price accordingly. Look at other Seawinds that are for sail for a reality check on the price. Decide if you really want to spend $10 to $20K upgrading the boat.
Also, you don't specify what you intend to do with the boat.
I used to own an Allied Chance. It was a great boat and much of it was solid but not all of it. The boat was on a lake so it didn't have to be as seaworthy as a boat on the ocean. I sailed it for a number of years even though it had some issues. When I sold it, the new owner wanted to spend lots of money on it, restore it, and move it to the ocean. I don't know if he did or not.

Difference between a power boater and a sailor out on the water: A power boater is going some place special, a sailor is already there.
