In general, the big takeaway is that once the car starts actually getting built, it'll advance through a number of codes in a single day. It's not uncommon for it to go from build scheduled to built in a couple days' time. The period it sits at the outfit center is directly related to the number of options selected. Not all options are installed there, but things like stripes, PSG, HK stereo, and others require a stay at the outfitter. For folks who like to ping the factory every other day looking for movement on their builds, it can look a lot like nothing is happening as it will sit there... and sit there... and sit there. Then, it will sit a few more days awaiting final inspection.
I can't stress enough that even after the car is done, depending on where you live, it will still take time to get the car. It has to clear customs at the port facility and the trip to your locale will vary on distance and by the number of hops it has to take. I live in FL, so that's almost the furthest it has to travel in their whole system. For me, it took about 2 weeks to go from the shipping yard to arrival in Orlando. Then, a week and a half to make it to my driveway.
Again 100% wrong...the only thing the upfitter does is stripes and painted hoods.
