Funny, the N54 is why I passed on several E61's and got an F10 even though I REALLY wanted the wagon. Nice none, but I couldn't sit around waiting for it to crap out.

The N54 spanks the N55 all day long and I wish I could have lifted the 80k miles old N54 out of my 2008 535 and dropped it into my 2011 535.
