If I had to guess which engine will offer better reliability over the long-haul: a BMW V12 or a Lexus V8, I would go with the Lexus V8. The reasons should be fairly obvious.
I don`t think it`s so interesting to see a comparison between the BMW 6.7L v12 and the Toyota V8. They are completely 2 different engine classes to be put in 2 COMPLETELY different chassis. They are both well made engines for their respective classes.
I agree with some of the points you made on the Bentley, etc., but I really don`t follow the reliability point. If reliability is THE FACTOR in determining best build, then there are very cheap engines that will run forever you look.

Lexus and MB make very nice cars. But, to compare RR and Bentley to Lexus or MB is feeble. It's a whole different league of car.
To start out, the chassis of the RR is completely different. Cheap cars like the Lexus are like the world`s best machine made, fused jacket. They start with a well made (but cheap) steel unibody and stack on everything from there (engine, body, etc....sometimes they attach sub-frames made in more expensive materials) Everything like your cheap Hyundai is built like this, but there is probably a huge difference between the Hyundai and Lexus too.
The RR is like a handmade, canvased jacket with a very expensive aluminum space frame. To be in this category, you would probably need to start out with an aluminum space frame or similar (carbon monocoque, etc.). There are a lot of super high end sports cars that use expensive chassis construction, but in the luxury sedan market , there are only a few.
