A8 purchase

Hello, everybody.

I intend to buy an A8 2000 built year 3.7l quattro. What do I have to pay attention to? For the V8 someone had created an extensive list. To my knowledge, the possible flaws of a used A8 have not yet been enumerated. Maybe you can help me.

P.S. Oh, yes, I'll keep the V8 as long as the maintenance costs don't eat me. It's hard for me to separate from this car.
