I don`t know who manufactures the MB original part, could be Lemforder.
I checked with our local dealers wholesale price, and is the same as you found.
Any of the after market mounts you see listed for the $10 - $30 range are probably all made in China, and may all come from the same plant. who knows?
I ordered a new Center support rubber piece and a trans Mount for our 240D, got it here on pelican. ordered the Fibi parts, and the box had FIBI stamped all over it, but there is a made in China sticker on the box. they are just a reboxer of parts.
We`ll see how long these last.
How long do you expect to keep this car? not long, then the after mkt parts may be ok. keeping it long term, maybe another 25 years, then go with the dealer parts.
I had my DL U-joint replaced by a DL Shop. they replaced the center support and bearing. 33K miles later, the rubber support was rotted and tore just about all the way around. Just guessing they used a Chicom part.
The original made it to over 300K miles.
