All- The only way I can see T getting to this number in 2018 is by selling the m3 in packages only. It's just not possible to pump out these cars that fast if it is all customized. Having been in the factory on a tour it seems they are moving forward via package lines. What each line is-I'm not sure. I know there are some here who want to completely customize their car. I do think you'll be able to customize colors-int/ext, tow hitch, wheels. You won't be able to get the pano roof in the 35k model nor will you be able to add it. You'll need to get the d model for that to be an option. Just an example. I think certain options will be forced upon you. It will more than likely be about price ranges. (just examples and I know prices aren't right) 35k-base model 38k-base model d 45k-model d with some options bigger battery 50k-model d with all options 60k-model L completely loaded largest battery I might be wrong and I could see why-just skip things in the manu line, but that makes a waste of space and time moving the car through it. Just my opinion. The 3 will need to be produced 15x faster than S.
