THE BIT THEY DIDN'T PUT ON THE BOX.
An electric-car twist in the Mercedes parts bin.
Tesla integrated Mercedes-Benz electrical and door-hardware architecture into its early premium platforms. Sourcing the mechanical window regulator assembly via Tesla Service carries a steep premium, while the underlying Mercedes sourcing code yields the item at an exact 60% discount.
SO WHAT'S THE CATCH?
The source claims a 60% discount, without a usable £ price or part-number match.
“The interesting bit isn't the badge. It's what happens when you search for the part behind it.”
THE INTERNET DETECTIVE'S CHECKLIST
Look for complete part numbers and revisions, make sure you're comparing the same quantity, and check the exact model/application. That's especially important with electrical, braking, steering, battery and other safety-related components.
