I asked my Sacramento dealer for coco mats when I ordered my 280 SL, and he dropped in the red/black coco mats from Vilem B. Haan. I was, and remain, unaware of any factory coco mats having been available in California at the time.
The Haan mats did not have a rubber (or any other) backing and they wore through quickly. As I replaced the mats a number of times -- the car has not been without some sort of coco mats in 34+ years -- I developed quite a nice collection of both the passenger-side mats, which got little traffic, and the sewn red/black over-the-transmission-hump coco connector piece that I'd dutifully removed each time my new ones arrived.
It's possible there were other, more complementary Haan coco mat colors besides the red/black (which cocomats.com replicates perfectly), but I grew to like the idiosyncracy.
Just like the other special item I asked my dealer to install -- the same Vilem B. Haan gear-shift knob that was selling for $157 on eBay this past week. That one looks like it could have been stolen from my car.
[Note to Douglas: if you have a moment, ask the cocomat.com people what ever happened to the mats they were developing to complement the Stone interior leather on the E-class. I was told they were a quick-trip-to-India away from production, but I don't think they ever appeared.]
