Audi V8 4.2

I want to buy a december-1992 Audi V8 4.2 automatic. The car appears to be in perfect shape and the engine sounds OK. All the maintenance books are there. The interior is also perfect. I found no strange corrosion on the outside/bottom of the car. Tomorrow I'm going to have another look/drive:

- Can someone give me tips on what details I should give specials attention to?

Thanks in advance,

Wouter
