Hi Munir,
there is a V8 Whatsapp group called "Audi V8 Leidenschaft" which, however, is in German Language. I don't know to what extent this will be helpful and interesting for you.
There is also an Audi V8 club called "Audi V8 Gemeinschaft e.V.". However, also here in German Language.
If that should still be of interest to you, please send me your phone number via PM.
Kind Regards
Thorsten
