Well this is an interesting idea. No clue what kind of stock they'll have and how much of a "sale" it will be but I bet there will be some solid options. Perhaps final year M3's or xDrive wagons, X5D's or 6 series Gran Coupes.
If you're looking to become a proud roundel owner before the new year, then ya oughtta sign up and see what the offerings are. You never know, maybe you'll get lucky and snag a 6spd wagon or 135i below KBB value.

He also has a YouTube Channel and thinks talking about himself in the 3rd person is really weird but knows it's necessary if he wants to be taken seriously as an automotive journalist.
