60Kmi on mine with minimal seat wear. But I keep it all the way back, and when I get out, I put my left hand on the sill beside the seat back and sort of pivot up and out on my left hand. I get in by facing to the left and then plopping my butt on the seat. then I put one hand on the door sill and one hand on the center console and lift myself up and then set myself down in driving position. I do it this way to keep the seat covers from sliding around under me.
Speaking of seat covers, I have the custom ones made by Christa, which I highly recommend. See other threads on this topic.
