I noticed a slight change in the data from Tesla that UWS are now available in the Design Studio for P90D and P100D. Is this a new thing or has that choice been there and I just missed it? If I ever buy another MS (which is not anytime soon!), I'd probably go for the UWS. I had them in my BMW Z4 I sold right before getting the MS, and they were awesome. I also noticed that perforated/ventilated seats might be pending as an option but not yet available as far as I can tell (I don't want to pull a wk057 and say too much now).
