Well, I think that's rather splendid! The rear does appear less impressive than the rest, but possibly those images are not the most flattering. However for me this is another example of good brand interpretation by BMW - what they're doing with Rolls Royce is sooooo much better than the footballtastic toot VW are churning out with a Bentley badge.
I don't have the budget or lifestyle for such a beast sadly, but I could see this having a much broader appeal than the awesome but rather ostentatious Phantom, not only on financial grounds. Okay so it's not discrete, but it's characterful and I imagine is a car to which one could become emotionally attached - not something that's true of an S-class, and certainly not the awful, awful, oh my God Maybach. I for one am pleased to see Rolls Royce continue to develop in these difficult times - good luck to them!
