How fast do you think it should be? I'm pretty sure BMW used to quote 0-60mph for the auto in 7.0, you aren't far behind. The automatic on the 128i isn't as good as the 135i. Also, are you using precise instrumentation for testing your time?
The bmwusa.com website indicates 6.1s/6.7s manual/auto.
I'm pretty sure those aren't the original numbers they put out when the car was released.
