When will you sell your X5?

As for the rest, well, you can see how many cars we have in the signature. Maintenance, engine swaps, etc. I have the bad habit of deciding "this would be better with that engine" a little too much.

To conclude BMW parts quality has declined with any certainty it would be necessary to do a sampling of some number of parts based on the total worldwide sales of that part.

As an example if BMW sells 100,000 of a part, the sampling generally would be 10% or 10,000 of that one part. The percentage can vary based on the reason(s) for the sampling. So if BMW sells 100,000 of the gasket you mentioned, your purchases would need to be 10,000. The gasket would have to be installed and fail. And confirmed that a comparable gasket didn't fail using the same criteria. The number of failures acceptable out of the 10,000 would be a quality control decision. Using 1% that would be 100 documented failures of the gasket you rejected and less than 100 of the gasket you did use.
