BMW is probably the biggest offender in this regard and you can buy the “unlock cables” for the older (<2015) models on EBay later they switched to a software lock, which you can also hack.

You can also tell there is no difference in the valves, pistons or pretty much anything else since the part numbers in the service manual are identical.

The only difference in parts comes to the trim and the breaks on some of the models.

We also see this in other things too you have differential pricing in say electronics and electronic components too, sure some of it is binning but not only quite often the "enterprise" tax is just the fact that these parts will be run longer and under more stress so their MTF is different.

An HDD in a home computer will be under very different loads than one in a NAS. And quite often there aren't many physical differences between the drives in some of the lower end models there are no differences at all and in some cases non-NAS drives might actually be "better" than their lower-end NAS counterparts.

What you are paying for when buying a WD RED isn't necessarily a more durable drive, you are essentially paying a premium for future warranty claims, it's essentially an insurance scheme in which WD RED NAS drives are defined as higher risk than say their Black or Blue series.
