There is the engine, and then there is the maintenance necessary to keep it going for 200+K miles. Turbo engines run particularly hot, frequent and quality oil changes are critical to keeping them going forever. BMW S** engines are the best at it, courtesy all the extra cooling and oil capacity, and cooling fans that run after engine shut down.
BMW's cooling system has been an ongoing problem space since E36 days. Those plastic parts get extra brittle from the extra heat. Now add plastic valve cover, intercooler, etc.
Toyota V6 turbos are going through main bearing pains, especially on US assembled engines and cars. Japan built engines and cars are rock solid. Hybrid Toyota engines have been pretty bullet proof for a decade plus.
Just following BMW or Toyota recommended 10-15+K mile oil change intervals is not good enough with turbo heat cooking the oil.

I don't think that's true.
Toyota includes Lexus, with customer base and expectations undistinguishable or even higher than that of BMW buyers.
BMW includes X-series many of which are cheap and sub-Toyota quality.
Majority of BMWs (60+%) are leased and barely (if at all) maintained. Lease, drive, trash, start anew in 2-3 years. Thus, buying a used BMW is a higher risk proposition than buying a used Toyota.
I would not buy either used without a PPI and access to PO's maintenance records.
YMMV,

P.S.: Currently own 1 product of each brand.
