Just a point of note - the 250 SL should have rubber mats in the foot wells, not carpet
Thanks Jonny,
Fully agree with your note here.
230ies and 250ies SLs exclusively had square weave carpets with rubber mats in the foot wells, but never carpeting.
If you today find carpeting there, it is not original, or aftermarket or both.
If those mats perfectly match your remaining carpet set you can be assured that your carpet set was replaced once in the past.
Original square weave carpet was made of wool and goat hair ... and that stuff ages with the decades. Just like your woolen clothing, e.g. pullovers...., those also do not show that perfect integrity any more after 50 years...
Even almost perfectly preserved original untouched cars have partly (strongly) aged square weave carpet with damages - likes Tempur's phantastic 25'000 miles original-untouched 230.
So, if your carpet is "almost" perfect it is utmost likely aftermarket anyway.
If aftermarket - it doesn't matter if you now solely change the "footwell carpets" then.
My advice is this:
1) Get the original rubber mats - available factory or aftermarket.
Then get non-original carpet on top (like ribbed mats or coco mats) or not - your preference.
or
2) Get new footwell square weave carpets from a supplier,
but first collect samples in your color - as many as you can get - from as many suppliers as possible.
You will be surprised how many different sizes and colors are available from the different carpet (interior) suppliers.
I would (and did in my case) go with the 1st choice - because that is the most authenitc one.
Just my 2 cents ...
