vstech and ps2cho
Both of you are correct. It is never a good idea to use anything except the best, EXCEPT when your money tree dies. We are retired without any income except SS and some savings. On this site Pelican Parts shows 2 flex disk. One is Brand O.E.M. for $76 and the other OEM Mercedes for $169.25. That is a difference of $186.50 for 2 flex disk. Nothing to you but a lot to us. Ismalley references a site that says they may be Lemforder. Would you accept Lemforder? The 'E500 Parts Manufacturer Quality List' indicates Lemforder is good.
My original question was have you heard anything good or bad about Brand O.E.M?
Please understand I will pay for OEM if I can't find a substitute at a lower cost. I am just looking for information that will help me make the decision.

Thanks again
