As far as engines are concerned, the inline-six cylinder has been BMW'* bread and butter for a long time now. I would say the 6'* have a better track record than the 8'*. There seems to be more that can go wrong with the 8'*. Plus there are more parts to pay for, 2 valve cover gaskets to leak, 2 more spark plugs, 2 more ignition coils, etc. Some BMW 8'* have been known for oil leaks.
As far as other items are concerned the V8'* are typically associated with BMW'* bigger, more luxurious, more techno-complicated vehicles, which can also have something to do with why the 8'* seem less reliable. With the exception of the 7 series BMW'* are fairly reliable overall. BMW is ranked pretty well in consumer reports and other publications.
