Hi guys, been a member of this forum for a while, so much info on here. I had a 335i, then an M3, then a GTR, then married life got in the way with a house and now debating between a used 2012 X6 3.5 or a 2011 X6 5.0
I love the V8 sound but all I read about the N63 is that it's a ticking bomb. Both X6 have 60,000 miles. I could put a JB4 on the 3.5 but still prefer the V8.

I've read a lot but looking for additional/new advice on the N63.
Once the major recall (Customer Care Package) is done should that prevent the common damages I read everywhere? What about timing belt, battery, other common issues from 60,000+ miles?
Any help or feedback would be deeply appreciated. Please don't say just stay away, but give me some more info/explanation. Thanks very much
