>> corrosion on silver trims

Polishing won't help.

>> didn't have the original Audi windscreen, spec says with shadeband but this one wasn't marked with the Audi rings and no band. Are OEM screens silly money ?

That's a pity. Check for corrosion around windscreen surround trim. I would walk away if corrosion is there.

>> when I used the interior lock/unlock switch in the drivers door, from rear-left of care there was what seemed to be a compressor-type sound lasting about 5-10 seconds after pressing Unlock. Didn't do it after lock. It did sound a bit odd going on for so long - any suggestions on what this could be ? Something powering actuators or similar ?

Leak in vacuum system. Can be difficult to fix, but doable.


Based on what you write is seems to be relatively tired example with owner who didn't car too much. It all depends on your priorities. You can find better car but it takes time. If you don't care too much about cars then buy it. If you think seriously about restoring that car to proper condition it is worth checking for better example.
