jin,
soon after being born, maybe 7-9 months my family decided to move back to UK and i have lived all my life in UK until about 3 months ago, when i decided to move back to azad kashmir.
AUDI RS4 or BMW M3 - i would pick M3 all day long with closed eyes blinded folded and hands tied back by back
Audi A5 /A6 or BMW 525m sport or 530 Msport --- sorry buddy audi would lose again in my books.
Audi A8 or BMW 750 - Sorry @mobile_jin Audi does not come close to BMW in Comfort luxury and CLASS.
THE ONLY thing Audi has over BMW is quattro system ---
BMW is for drifters.... not really, any car can be set up for drifting.... drfting is a japanese funtime which hasmade its way to europe and USA... we also drift cars in UK, but only in modified jap cars.... IE nissen silvia s12/s13/s14/s15 etc etc etc....
BMW give you performace when needed and luxury and style comes freee..
I will give you one expamle.... go to any company HQ... look at the directors parking .... you will see more BMW than AUDI...
