These are the wrinkles I'm talking about. Actually I liberally applied McGuiers leather conditioner to my seat and it has reduced the wrinkles for sure. Gave it time to soak in a few days. But when I sit on the seat I notice the top part just stretching the leather and all the creases being made by my weight. I figure there's no getting around that, although my old 328 leather has no wrinkling issues whatsoever but it also it a much more stiff leather.
Those dark spots you see on the leg adjustment piece is from the leather conditioner, apparently that's a different kind of leather that shows much more shiny than the navillo.
