I am considering purchasing a 2005 Phaeton with 54K miles. Does anyone have any recommendations / cautionary advice? I know the car is incredible, but what are some of the gotcha's that I should be aware of? I will purchase the certification (2 yrs, 24,000 miles).

How about parts? I am in the US and am concerned that because the car is not sold here any longer that parts will be expensive (shipping).

I know that the car requires premium gasoline and that oil changes go for about $140 per 5000 miles.

Anything else that people can forewarn me of regarding maintenance / potential shop time with their experiences?
