The cocomats we ordered for our 135 were delivered yesterday. These are quite a bit more substantial than the factory mats and are extremely durable. We've had a set in our last 2 cars and they wear like iron even in a location that has a long nasty winter. When they get dirty I just hose them down and then scrub with a brush and a little soap and they look like new again.
For some reason I can't post any pictures, but here's a link
to a few pics showing them installed (click on the thumbnails for a larger image).
These may not appeal to everyone, but we've been quite happy with them.
