Deck delamination/creaking/soft.
Leaking around chainplates (rust visable below deck around bulkhead).
Osmosis.
Leaking windows.
Cracks around stanchion bases.
What engine?
Little of the above is really serious. Generally pretty good boats.
You need to check for water ingress/delamination around the chainplates which is not a big deal to fix, and get a surveyor to check for moisture in the hull, they are old enough to suffer osmosis but this can be a bargaining point. No boat ever sunk from osmosis.
Hatches/windows are usually a function of previous owners' refits. Observe and judge. I'd be much more interested in the hull-deck join...
I have one and adore it. As a small classic GRP yacht there are few to compare.
I looked at one which turned out to be an import from South Africa where they were made under licence. This may have been an unusual case but VAT and CE issues made me run away fast.
