I am still unaware of being able to buy an X5 for less than sticker price in Chicago. However, that could change as dealers start to get inventory. I have noticed on the way to work every day, as of 3 weeks ago, Perillo BMW on Clark St now has inventory for the very first time. There's a mahogany one in the showroom and if you look up to the 2nd floor windows at the corner, there are about 6 white and silver ones up there. See if they are willing to negotiate now. I bought mine at Patrick BMW in Schaumburg and the service is really good there but have had service at Perillo too and they seem to be just as good.
