Good research! If you want all those packages/options, you'll need a 2013 (to get M Performance and Heated Steering Wheel). Will be hard to find a 2013 M Sport with most of those packages/options for 50K, but I wish you luck!
It may not matter to you, but if you want the LED coronas you will need a 2012 or 2013. The only 2011's to get the LED coronas were later build x35d models (March 2011 and later). There are many aftermarket bulb options, but nothing on the market that will duplicate the OEM LED coronas on the 2012's. Lots of threads on this topic
Here's some xDrive50i's with lane departure warning -
S5ADA - SPURVERLASSENSWARNUNG (Lane departure warning)
5UXZV8C51DL899050 - 2013
5UXZV8C50CL423967 - 2012
5UXZV8C58CL423604 - 2012
5UXZV8C55CL422846 - 2012
5UXZV8C58BL419048 - 2011*
*not sure I've ever seen an X5 this heavily optioned. The only items I can think of it's missing are M Sport and the optional 20's.
