[Robclat]

First time X5 wannabe owner. Upgrading from and X1 and need some advice.

Whittled it down to two contenders

- Dec 2016 Space Grey on black 469m with black Dakota

OR

- Sep 2017 Black Sapphire on normal 469m with ivory white.

I'm really interested in any major system differences - iDrive in particular, can't figure out if 2016 has 5?

Appreciate the help.
