My fronts were replaced at about 75k, and my rears at about 90k (although they still had life left, I had already bought the pads and was painting my calipers anyway, so I replaced them). Now at about 95k my fronts are already gone again! Darn semi-metallic crapola. As much as I'd like to buy the best for my VX, which most seem to agree are the OEM pads, I've got a lifetime warranty with Autozone, so even if I've gotta replace them every year or two, they're still free. When I've got more cash to spare maybe I'll consider going back to OEM.
