I checked with Curt and they list Curt Trailer Hitch Receiver - Custom Fit - Class III - 2" Item # C13316 as a fit for all models of the 2017 BMW X3. But what that means for your M Sport version is that there could be additional trimming required to install the hitch. For more information on trimming please see the instructions for this hitch which I have linked for you.

If you plan on doing some towing I recommend etrailer ball mount kit # 989900. It comes with 2 ball mounts; one with a 3/4 inch rise or 2 inch drop and one with a 2-3/4 inch rise or 4 inch drop. It also includes a 1-7/8 inch ball, 2 inch ball, hitch pin with clip, and a storage bag.

If the ball mount kit does not have the right rise or drop to tow the trailer level, use the link I have included that explains how to measure to choose a ball mount to tow the trailer level.

And for trailer wiring I recommend # ZCI Circuit Protected Vehicle Wiring Harness w/ 4-Pole Flat Trailer Connector and Installation Kit Item # 119250KIT. There is no splicing into the vehicle wiring required to install this harness! I have linked a video showing an example installation on a similar vehicle.
