Gocy,
I like everything LJ said but, in particular, I think "treat the bike as a new build" is brilliant. The bike may be running and seemingly fine, but I think, with bikes of this age and in different states of repair, it is correct to believe that things are a bit worse than they appear on the surface. This doesn't mean you can't get some riding fun out of it before the work begins, but work there will be.
I wouldn't suggest that the forum can be your official consultant for purchasing or not purchasing, but if you had the chance to post a few photos here or, maybe, a video on YouTube, I am sure you would get some careful eyes and ears commenting on the condition.
As for being in Cyprus, I was scheduled to be there today, believe it or not, but the work got changed to via email and telephone. (Note to Emilios, my alternate trip to Londan was also cancelled). Nevertheless, the project I am involved with should get off (and out of) the ground someday, and now I will have two "A" ers to visit with.
