I’ve had three 126 Chassis 300 SEL Mercedes. I used after-market motor mounts from two well known suppliers with horrible results. I finally decided to go to the dealer for genuine MB motor mounts. The mounts cost me about $100 for both sides from the dealer. For some reason the right side mount is over twice as expensive as the left side. I don’t think I got much more then a year out of the after-market mounts, and it looks like the OEM’s are still OK at well over two years. The right side really takes a beating from the exhaust manifold heat. Has anyone experimented with a more robust heat insulator then that OEM little plate that’s on the mount?
