Tried researching this for you. Everything I read says there were only 12 models of the 1994 Mercedes E60 AMG made with this leather interior -- which is only referred to as the "Limited" sports interior.

It sounds like you have a really rare model on your hands. Unfortunately, I can't find the name of the insert style/design. Try calling the Mercedes-Benz Museum?

sounds crazy but almost looks like they laid a piece of chipboard at different angles and airbrushed?

that’s just about what they did bob

Could you get grey leather and leather dye and do exactly that. Made your own?

Hello Rusty,
yes, I'm familiar with that Mercedes-Benz insert leather. I don't know the exact name but it was a limited edition of the Mercedes-Benz interior 'designo'-range. It came in different colours (grey, green etc.). Can't imagine that it's still available (or wanted - no one was keen on my stocked hides, yet...). But you could easily dye some...
