That's factually incorrect. I'll give a positive example of the E30 heater valve, which was explicitly redesigned in house by BMW Classic. I'll admit that they did nice work on this one!
As for testing, well, who the hell tested the spark plug tool that couldn't fit in the S14 spark plug hole? They shipped it! It literally had one job!

We have gone from quality issues with all BMW parts, to specifically classic parts to speculation that the quality will decline when the E53 parts become classic parts. Nevertheless, I respect your opinion.

I can make a good argument that the average level of quality in newer BMWs is a lot lower. Just look at how well N20s/N54s/N55s are aging.
But it's a lot harder to make a statistical argument based on anecdata. I have hard evidence of BMW substituting low quality, or even completely unsuitable parts on the Classic side, and in a thread about the longevity of the E53, that is an absolute concern.
