^ So runflats are your excuse for the almost 300 lb weight difference? Are you forgetting that the A8 even has AWD with that ridiculous weight difference?
Stuff like Nappa leather, navigation, iPod/USB are already standard on the A8... It's a porker, no matter how you try to make the numbers work in your favor. Simple as that.
That being said, you have earned a spot on the coveted Ignore List™. Your constant ignorance and baiting are waste of everyone's time.
