Thanks guys, I just picked my car last Friday. This time, they drove 60 miles without telling and at a different dealer. They said they cannot duplicate the problem, but SA saw it b/c I drove it in while it was doing the misfiring. Anyway, they printed out report from the car. It shows that I've been filling it with medium grade quality gas/89 octane 17 times out 19 which I never did. SA said that there is nothing they can do. He suggested that I should contact BMW NA which I currently am, and try to get them to send out their engineer to look into this.
I will take Andreo advice if BMW NA isn't going to do anything in the next few weeks and bring it to BMW AG.
In the meantime, I'm stuck with this POS car.
