In Germany income inequality isn't as extreme as in the U.S., and meaningful amounts of stock compensation is the exception, not the norm.
Healthcare is universal and has pretty high standards, so there's a smaller pool of perks that come with employment - corporate cars being an important one.
So the purchase price does not matter much to the user of the car (who often has influence on the model bought - this is a perk/benefit after all) other than it being within the approved range.
The monthly "personal use" tax matters a lot, because it attaches to the employee, not the firm, and firms cannot reimburse this tax directly.
So for example if for a larger firm the purchase limit for that position is €55,000, employees will normally try to max out that purchase.
The tax incentive will increase net salary by €275 per month instead of €550 - a 7% effective raise if net salary is €4,000.
As a result I expect 90%+ of the German corporate car sales to shift to hybrids and BEVs.
