If so she looks like a pretty typical IOR influenced 80's racer.. fairly spartan interior, but the glass work looks tidy enough. It would take some additions to make it into a good weekender, most likely, but she looks like she'd be fairly quick. Boats of this type from that era tended to go upwind very well but get a little skittish downwind in a breeze.
I trust they have the normal kind of marine survey system in place there, be sure to have it thoroughly checked and since you're there I'd think that some of the locals would have some knowledge of the builder and design unless it's a total one-off...
Could be a fun daysailer, don't know how to convert but a price tag of 800K for a 27 footer's a bit scary!!
Edit.. went back and translated that page.. pretty funny. 'climb' = upwind, I guess
