Pretty sure I got a glimpse of the M3 assembly line at the Fremont factory. I could see two bodies in this line from where I was standing. How can I tell these are M3s? The tail lamp is flipped up on M3s vs S - you can see that in the pic. You can't see it in the pic but from I could also make out the trunk shape of the M3 on the back vs the hatchback. So fairly certain these are M3 bodies. This is visible from the Fremont factory supercharger. So anyone planning to charge there can check it out.
