I also have my first BMW, F31 330d m-sport. I nearly ended up with an audi A5 3.0 quattro s-line... But it's true what they say, all said and done the BMWs drive better.
The Audi interior was certainly very nice though - it was a close call. But the 3 series was simply the better overall car. And god it shifts, no way the Audi can match it's speed or efficiency like for like.
Bit odd being branded as a BMW driver for the first time in my life!
