The 240D that I drove 450K went that distance on the original rotors. I used beck arnley standard pads. They were soft and didnt last as long as other pads but were easy on the rotors. Replacing pads on a 123 car is probably quicker and easier than most anything put on the road so changing pads a little more often to save the rotors made a lot of sense.
