I just did this too. Looked for about 4 weeks. Found the one for me. It took a long time and I had to be ready to pounce when I found it. PM me if you want to know what I learned. We can go voice to voice...I still find that the best way to ask and answer questions. I learned a lot in my search and am happy to share if it is at all helpful to you.
I found an S85 with tech, autopilot matte obeche and lighting packages. Textile seats, no Pano, no air suspension. 12,000 miles when I picked it up. Ten months old Dec 2014 build.
They're out there. Just be read to move fast. I'm very pleased and 100% confident I picked the right one.
The only thing I wish the car had is the next gen seats. I didn't want pano (leaks and squeaks and not my thing), and air suspension (never had one and never thought "if only I had air suspension"). So except for the next-gen seats, I got exactly what I wanted in one 3 colors (wanted dolphin gray, titanium or blue...got gray).
