Stealth.Pilot - thanks for your feedback! I didn't know about the leather differences (my M6 has full leather dash - i like it, wouldn't want to give that up. Where did you hear the details on where the leather is? My dealer knows less than i do at this point).
I think i will do 20"s, forget ceramic and keep the rest. I may go with Platinum if someone can confirm that it is like a tan (vs. some other goofy color). Good to know on piano - i may change that. thanks!
