And quite a few of us own one if you have any specific questions. But since it's the largest production run of any keelboat (over 6500 made) there's plenty of info on the internet about it. Heck, the wikipedia article has pretty good info.
I have moved on to another boat, but I've got nothing but love for my '85 C30. As stated above, tons of info out there for any questions you might have.
