Hi guys!
After going through several bmw platforms, n20,n55,s55,b58, I think I want to move on to a m6 gran coupe this time.
The one I'm looking at has pretty high mileage 77k, comp pack and all the goodies, good oil change history.

Only thing holding me back is horror story of a friend with a n63tu locked up at 69k out of nowhere.

Now, I work on my car, and plan to do all injectors and coils if I get it, and I over maintain my cars like crazy. Are there anything else I should plan for, or, should I just pass on this and look at something else?

Appreciate the feedbacks
