Hy!
Rust over the rear window isn't rare.
You also should look at the brake discs in front.
Check the mileage because by 90.000Km is changed the Zahnriehmen and this costs as of 600€ !! Check the Servoöl because perhaps is leakily the steering.
If you know also German, then watch the purchase help on Audi V8 . If not, then you can take this translator .
Excuse my bad one English.
I gelobe recovery!


Greetings René!

Denk immer daran, MIT DEM ÖL NICHT SPARSAM SEIN !!!!
