which is to say, without any headlight wipers and motors (the euro ones cost $700 the pair from ebay and arrived with one dead headlight motor that needed to be rebuilt)
You could take the OLD valance(s) off the car and go to a hardware store, and look for ones for 50 cents each that pops into the hole!
Paint each one before popping it in the valance hole. It would be so hard to tell from 5 feet away, it would be enough.
If you are feeling rich, have a body shop simply really plug up the holes, then sand down or respray them in matching paint, (or YOU did the prep work yourself on the valance(s) and took them to the place, remembeing that 90% of the body work on a car is the prep, and you will save a a pile of dollars if you do the prep yourself)
....and anyhow, usually in a couple of years of heavy driviing, there will be a lot of small stone chips on the paint in the valance(s) you might as well have it painted anyway...it s another way to save most of your money and still get what you want
Good luck whatever you decide to do, Carlen.
No problem if you want to avoid the Mercedes Benz dealers if you are trying to save $$$$.
Thank you for the comment about what is NOT a flgapole but is actually a W126-Japan only dealer accessory (though an official Mercedes Benz part.)
Back in the 1980's left hand drive Mercedes Benzes were a huge prestige item in right hand drive Japan and these poles, available there for the W124 and W126 cars were available to mount to make it easier to park.
They work exactly like you think they do, mine has the silver star on top but another option was the plastic star with wiring down the star, which lit up at night, and was cool until the plastic got yellow.
Here is one seen at a used car dealer of exotics in Japan called Garage Current in Yokahama: (sedan)
on a coupe:
You could ask about them at the Mercedes Benz Classic Center USA in
in Irvine, CA

(here) or call them up,
which had never even heard of them, and I had to show them one on a 560SEL in their own parking lot but you could call them and ask.
I was given one of them for free from a generous member that had this one for a w124, which I cleaned up and had intstalled.
The diplomatic flag poles were another matter. Also a Mercedes Benz accessory, they came in pairs, to mount flags on each side front fender, and I don't have the parts for either.
Not sure if you want flag holders, (two, one for each side) or the parking pole.
Anyway thank you for complimenting my car, I appreciate it.
Later.
