Try Autocouture Motoring in Fair Lawn, NJ. They're good guys, and even though I've had mixed experiences with them when asking for something complicated (long story), they always sorted it out in the end for me, so I still stand by them.
And for an alignment I think it's $150 which is less than what BMW charges. I would trust them over the "hole in the wall" garages that are everywhere. Sears once mounted my tires facing backwards. Another local shop almost let me drive away with a lug nut missing. Autocouture would never do that.
