We were at our local BMW dealer taking delivery of a 3-series for my wife when I spotted a brand-new convertible M6 sitting on the lot. The color was absolutely breathtaking--it's a new BMW (?M-specific) color called San Marino Blue. Not as purplish or dark as Interlagos, and not as light and bright as LSB. It has amazing depth and richness.
My CA started the car for me and revved it a bit--sounds good. Rumbly but refined V8, with some nice pop and burble on the overrun. Can't touch a naturally aspirated BMW V8 or V10 in the sound department, though...
Oh, another thing--the LED headlights are amazing.
The sticker? $127k.
