In my opinion I believe the n62 motor in the 550i is pretty reliable. I bought one about a year ago with nothing wrong with it so far at 114xxx. Gaskets were changed by previous owner no idea when but holds a lot longer then the n52/n54 motors so I was told. The only problems that I know about these are the fuel pump. They go pretty quick and easily but that's pretty much in every BMW. Pretty good on gas surprisingly but am looking to get rid of it soon. I bought to build and with the BMW v8 motor theres really not much options for it. There is power in it stock as it is but I'm looking to get a n54 and build on that. The 530 and 528 are reliable as well. Pretty much all the motors should have similar issues other then the n54. Problem with those is the turbos but that's when you single top mount it once they go. I believe n62 internal wise are built a lot stronger. It's a great daily/family car but to build, not the best option unless you have the money for it.
