Best way to be sure is call / contact your local dealership and verify the part number posted in the auction (210-240-20-17) however, this only works if the auction is for a genuine MB motor mount.
Be sure to inquire about warranty, quality, and authenticity of parts!
From what I understand many aftermarket parts are substandard when compared with the real MB deal - and at such a critical location I'd definitely think twice about it.
Cheaper in the beginning almost always end up more expensive in the end.
Why not contact a BW member/sponsor such as Ron at http://germanstar.net and see if he can get them? Nothing wrong with fastlane but if you like the site, may as well help those who also do.
