I'm looking to buy a new X4 M40i and am debating about getting a 2017 or waiting for a 2018, depending on timing. Its my understanding that the 2018 X4 (as well as the X3) will be built on an all new and improved platform with the X3's to be released in the near future and the X4's to follow. My question is when will the 2018 X4 M40i's start to be manufactured, released and start showing up in dealerships? I have asked three dealerships and they don't know the answer to this question. They tell me the 2017 production is coming to an end in the next few weeks with less than 10 "slots" still available to use on an order. I have done a lot of online investigating and found general statements and the 2018 X4 release such as late 2017 or early 2018. Does anyone have any more definitive info on this? Thanks!
