Coming from e53 - E70 Achilles Heels ?

[Russianblue]

I am looking at a new to me 2012 E70 with 76k miles.

My e53 is going to my daughter in a month or so when she gets her license. Still drives great with 176k and should be good for 30-40k more (if the tranny holds) to get her out of high school.

Obviously the e53 has a number of areas that make all e53 owners cringe, but I assume I can take care of most of those things on an e70. I am wondering however, what the 'big risk' breakpoints are on the e70, similar to the transmission on the e53.

I am hoping to get about 100k out of this new purchase and am fine replacing suspension, cooling system parts, VC gaskets, OFH gaskets, door carriers, window regulators and all that stuff BMW just can't seem to get right after 20 years.

Is there a list anywhere of 'things to look out for' with the e70? turbo? driveline? I'm trying to narrow down to repairs which, let's say, might be more than the slightly above average home mechanic can handle (like a tranny replacement, but not a diff replacement) and may cost over, say, $1000-1500 in parts or similar.

I know I am taking a risk going this route. I just don't want to look back and say "Crap, I should've bought a 2015 CPO and I wouldn't have spent as much money as I have in repairs on this jalopy!"
