Thank for the heads up, Today I just bought a pair of plastic car ramps so I can start on the break job on my W124 E420. Also I'll have a look at the S500 and see from underneath the car where the leak is originating from. Buckwheat you said it might be possible that its comming from the tran coolant line, if so should the liquid be coolant? The leak I have is motor oil. I was wondering if there is a oil cooler line in the S500 that is attached to the oil pan? Anyways I'll keep looking. Just bought a lottery ticket, hopefully I win and not have to fix the problem myself.
