Wether you like it or not, the lines are pure, the design is consistant and balanced. I'm not a fan of new BMW design but it looks quite nice for me, as well as original.
The old Jag' XKR is absolutely stunning: elegance, refinement, elegant aggressivity of a feline...
The new one looks like it's crying for its design, its low chin is too far ahead (especially compared to the sideskirts), the deck spoiler is stupid (they could have it integrated to the trunkdoor at least). The nice design cues are the overall lateral shape (from Aston Martin) and shape of lateral windows (also taken from AM, except the rounded rear end).
