This is one of those boats that are hard to peg. They were pretty comparable boats to the Hunters of that era (Hunters were actually prettty high quality in that era).
The Endeavour 32 began life as the Irwin 32 which was a nice racer/cruiser for its day. When Endeavour bought the tooling, they basically cheapened the boats in a lot of ways, and in doing so compromised its sailing ability by eliminating the Irwin's centerboard, reducing the amount of ballast, shortening the rig
, installing lower power winches
and lower quality hardware, and so on. My family owned 2 Endeavours from this era, and build quality on these early Endeavours really was not very good.
Nearly 30 years later, if these boats had a caring owner, factory electrical issues would have been address, any structural issues will be visible, perhaps the cheesy deck and cabin hardware has been upgraded and so on. Or, if they were just sailed and put away wet then I would expect the boat to be something of a project.
