Audi a4 vs/or bmw 3series

[DomPritchard]

Hi, allways like the 2008 bmw 320d m pack touring. When i was looking to buy one i couldn't find any i liked. So i ended up buying a 2008 audi a4 2.0tdi touring. Nice car but im a bmw man myself. But now i have found almost the exact bmw i wanted. Priced allmost what i could get for mine.
So the question i need help with is
Audi or bmw??
And why?

Cheers Dom
