Welcome. You're looking for the "911 Technical" forum. This is the turbo forum you've posted in. There's also an "Off Topic" and offshoot "Politics and Religion Forum" (PARF) that you've apparently found.
You can post about anything in those places.
The car you've picked out looks great. I can already tell you know that the AC doesn't work. No need to guess. Particularly if it hasn't been used in awhile.
I don't have a printout of the options decoder (it's at home), but if no one chimes in I can look up those mystery options for you. Apparently there's a way to do it online, as well. Do a search, as someone posted the link to it last month on this turbo forum.
edit: Found it. Check out post #44 on this thread (over on the Technical forum):
What did I just buy? Real or not? Good or bad?
