The f06/f12/f13 6 series stands on its own...wouldn't have bought one if I didn't think it was all that.
But I can see the evolutionary design that went into the new 8GC. It probably would have been the next gen 6 series if BMW hadn't killed it off. There are some things that are "meh" like the absence of the Hofmeister kink, the all digital instrument cluster (heck, I don't even like the 6WB on the f06/f12/f13...it reminds me of the 1980s) and all the air scoops (are the fake or real?)...and the exhaust openings don't light my fire either (make them a real exhaust tip instead of a cosmetic "ring" around round exhaust pipes that are visible a few inches inward).
But Y'ALL...they have 2 sunroof panels...and surely at LEAST one of them has to open, right?
