Actually I guess I got lucky. The link off this website to allpartsexpress.com has the genuine MB window motor for the left side for $137.00, which is the side thats broken. For some reason its about $50.00 cheaper than the right side.

I have changed out entire window regulators before on domestic vehicles but never on the MB. Is it difficult? Is removing the door panel tricky? Thanks.
