I am seriously considering an N55 535i BMW for my first car as it is relatively affordable and I love how they sound, look and how easy it is to modify them to make power. I have done hours of research around common failure points of an N55 and how to fix them and am comfortable working on cars.

The main reason I am asking is because I’m scared of reliability, although the n55 is significantly more reliable than a n54 it still worries me and makes me not want to even consider buying a BMW.
