dealers usually take a chance with those "waiting lists" - I walk up to a dealer, look at the cars on the lot, ready to walk out, dealer asks me, what i am looking for - i say, E90, black or white, no more than x miles... hence, i created a waiting list... i might buy it once he has it, or not... if i walk into several dealerships, with the same car in mind, all of a sudden i create a demand for my specific choice of a car, thus driving the price up... not good for me... lol...

on your selling side - you don't really care, if you get a good deal, take it... otherwise, enjoy the X, ignore the offers, just like the JCL said...
