[xj-s] Power Window Motors

I don’t know why it took so long to observe the obvious, but here goes:
Over the last two years, I have upgraded both the window motors on my '89
from the Delco to the Bosch motor & regulator.

A few weeks ago, I found myself in a Mercedes repair shop, and noticed a
window motor lying on the table. Dang if it didn’t look exactly like the
one I put in my XJS. Which leads me to speculate: How many other cars use
the same motor? Audi?, BMW?, Volvo?, Saab?, Opel?. A wrecking yard Bosch
motor, in conjunction with a new Jaguar window regulator may be just the
ticket for replacing those crappy Delco motors without bleeding from the
ears at Jaguar’s price.
