Hi, I am new to this forum. I used to own 2014 F10 528i M sport couple of years back but sold it due to long term work placement abroad. Now I am travelling within Asia so its time to get a car again. I am deciding to go for 535i with 6IL twin scrolled turbo version. Most likely 2011 version. Anybody have experience with this spec? The things to look out for and maintenance wise? Any advice here will be much appreciated!
