Car in question is a 1986 300D Euro (no turbo).

I am now on my second new belt, after having a reputable shop replace the tensioner, the belt shock, the fan pulley, and of course the belt itself. The first belt was done as an emergency repair by another shop on a long road trip coming back from Maine.

It appears as though it is shredding on the inside, towards the motor... again. But I'm not entirely sure. The texture on the outside appears to be "smoothing out" - is this just the way these belts wear in? The ribs appears to be fine I don't see any fraying. But I'm worried I might be on borrowed time.

Opinions?
