I recently had someone admiring my 300CD and they asked me:
Have the jack holes always been open or were they originally fitted with plugs from M-B?

A question I'd never been asked and never considered myself.
Does anyone know if plugs for jack holes were ever standard on the 300Ds/300CDs?

Thanks-

They originally had black rubber plugs, shaped like mushrooms. They must still be available from the dealer.

Having bought several W123 cars new, the jack hole plugs were an option. I see them for sale on Ebay quite often.

I bought the ebay plugs and they are fine. Prior to that I used rubber corks from a big box hardware store.

I still have a few. If you need some, PM me. AFAIK, they were an option or dealer-purchase item for the 123s but standard for the 124s.

All good information and helpful. Thank you!

and the 126 cars, both generations.

My 123s never had them but my 126 does.

I have even seen chromed plastic ones.

Mechanics have always told me to clean out the jack holes, throw in some grease or anti-seize, then put in the jack plug
