Epic post, been 2.5 years since my M4 order but even that was my 3rd time at the process. Got so good at it that I even watched the live stream at each of the 3 Panama Locks. It's really sick when you spend this much time tracking it, but I even tracked the delivery from port to dealer on the semi.
Looks like I'm about 5 months from doing it all over again, probably f82 M4 again.
