1) Where can I download the current 2015 M5 owners manual? It's not on BMWUSA.com.
Here is the 2013 Manual. The 2015 manual shouldn't be significantly different.

2) Did your M5 come with the Michelin PSS or are some being delivered with Pirellis? (I prefer the PSS)
PSS for me. Some have had the Pirellis (a few threads on the topic). Most prefer the PSS.
3) Is there a noticeable difference between the comfort and sport settings on the suspension?
Yes. It is more noticeable with aggressive driving on twists, etc.
4) How many manual and auto settings on the MDCT? My M3 had 5 each.
3 for each (Drive and Sequential). See pages 70-73.
5) Anyone that came from a 6 series - thoughts, impressions?
Not myself, but many on here have had both.
6) What material is on the console? I know it's not the same as specified on the dash.
