Ay Perttu,
the differences are in the later models 1991-1993. Audi changed some electric stuff and the main elements of the climate-control. So I think you should try to find an earlyer car with the same engine as yours (so the control-boxes are the same) (control-boxes...? right word...? Steuergeräte in German...), besides the fact that the cars after 1991 are more expensive.
I'm still not satisfied with these control-boxes...
The computer that controls ignition-point and things like that...
And if possible you should try to find a V8 with the same extras, interior and colours, sometimes little things like switches or locks get broken.

Yeah, yust decided to take some lessons in technical English. Would be better for me.

Greetings from the very north of Germany

... control boxes...?

Alles wird gut.
