Thanks so much for the wisdom! Good to know the air bags are not necessarily faulty.
The dealer I bought from has a body shop, but is about 45 miles out of town; I'd rather use them because no one in their right mind gets service from Manhattan BMW (pun intended). I was thinking of asking to have the car flatbedded to Spring Valley, rather than driving it up there goodness knows what could be wrong with the car. Overly skittish of me? My daughter took photos, will post them when her teenage self gets them to me.
