Don’t be scared about the N63TU2. They made major improvements compared to the N63TU. Although it is not as bulletproof in terms of reliability as the N63TU3, I’d say it’s still generally reliable. So reliable that I was willing and able to get an 2018 M550i and 2016 750i. 750i has 67k miles and M550i is at 45k miles… knock on wood
