I took a group tour through the Spartanburg Assembly Plant last evening. I had also toured it during Homecomine '98, but plant production was actually shut down for the event. This time the plant was operational and the tour was fantastic.
I noticed several Y2K M roadsters and coupes that had a different rear view mirror. It is still an oval, but it is several inches smaller left to right. Its height appears to be approximately the same, not exactly sure. The surprise; it now appears to be SELF DIMMING! It has a small electrical pigtail coming out of it going up to the plastic where the dome light is and it has a small sensor at the very bottom in the apex of the arc. I am very glad they have made this change. I need to head to my local dealer to see if this is available and check its function and price. If anyone else finds out first, let us know.
