Best time to buy

[asnpcwiz]

The wife and I are sold on the new X5. We bought the E53 brand new and still love it. Waiting on the release of this F15 model as the previous version was one we decided to skip. So assuming it comes out in the next couple of months, is there any chance that Christmas may present some good rebates? We bought the A6 during Chrsitmas of 2012 and got a great deal. The wife is skeptical about a similar deal on a new BMW so close after release...and the old saying of an SUV during the winter. She thinks maybe next summer...July 4th may be a better time. Is there something between those times that would be better to buy a new X5? Thoughts!?!
