I'm not sure which engine you have, but if it's like my 2.6 in my 300E, you can make the repair yourself. So why give up now? If you have confidence to make those repairs, you can repair the upper half of the timing cover seal and gasket, with enough patience that is.
Simply remove the dist. cap and rotor button to begin with...and then you will see what is involved from there....The worst thing you would encounter is breaking the "drivedog" (the metal piece which is bolted onto the cam, where the rotor button is attached to the camshaft)....and the replacement part is $20, and two versions are available.....small and large diameter of the hole in the cam ...but if you get a puller, you should be able to remove it without breaking....and upon reinstallation spray lithium grease into the front of the cam, so it won't corrode and get stuck again.
Just be sure to replace the cam seal and the rubber gasket on the bottom of the upper half of the timing cover, and when installing, oil the lip of the seal, and walk it around the cam lip with either your finger nail or suitable object that does not cut the seal. Also place some red rtv on each side (left & right) to seal at the head and lower half of timing cover, making sure each side is clean first (especially the left side which has a recess to the head gasket....this is where the leak develops....spray carb cleaner and let dry on left side before rtv). Just don't use any rtv on the rubber gasket that lays in a ridge, but this is where the tricky part is....to get the seal lip to seat on the cam and the rubber gasket to make the seal at the same time while pushing inwards toward the engine.
Your dealer would probably want to charge you $500 or so to do this, but I know you can make the repair, and save the money. You probably do have the 300E with the notorious leak....like I had. Let us know what model of MB you have....but sixto is probably right....sounds like the leaking 300E.
Good luck, and hope this helps.
