Hey it was good meeting you today dude.
Instead of starting a new thread, I'll just put all of the high-res pictures I took here on this thread instead.
I took a few pictures that show which parts are leather and which parts on not leather on the "Full" Leather option on the M3/M4. As you can see, it's missing leather on the lower part of the doors and on lower parts of the center console. The dash and the tops of the doors look good though. Overall, I think it's a very sporty interior, but not a luxurious interior.
Enjoy!
