Considering making the upgrade E53 to 11'/12' E70, few questions

[jc1surf]

Hello fellow E70's...First thanks in advance for any and all inputs. I currently have a 2005 E53 w/ 156k on the clock. Was thinking of upgrading to the 2011 or 2012 E70. I was considering the Range Rover Sport but seems like the reliability is worst.
Anyhow, found a few Platinum Gray w/ oyster int. Does anyone have the Oyster interior? how's the maintenance on that particular leather/color? ie does it get dirty rather quickly and or hard to clean? I am a smoker and i am just worried ash or something might be noticeable. I do love the contrasting color combo. However, I am very ocd with interior. Minus the smoking:
Also, does the brighter corona lights as DRL only come stock in 2012 ?

thank you again.
need to update my sig...sorry
