Congratulations to robbdom, who is the only person in the world who prefers the early Evora's interior to the 400's, besides me. Clearly he is a man of taste and sophistication.
Rob, as Number 6 says, the condensor is not too terrible to replace. Your dealer will need to remove the front undertray and bumper, and may want to remove the front clamshell; though I did the job myself without removing the clam, doing so would have made it easier. The condensor itself was a few hundred bucks -- and you'll need to replace the dryer too -- so if indeed that is the problem you'll be looking at something probably a bit north of a thousand bucks or thereabouts.
About the clutch, don't worry about it. In almost a decade on the forum here, we've seen very few cars blow clutches, apart from some early ones that had some kind of build issue (run of bad parts or something). You're not going to blow up the clutch on your Evora.
