That was my question also, how do they know? I talked to my dealer today and he had nothing from Ford. So maybe my email was an error? Who knows. This was fun and interesting before but at some point it has to stop.
I screwed up on this too. When I gave up hope on a 2-door and went to a 4-door soft top (Badlands) the modular bumper wasn't listed, it said "steel bumper". I didn't even know there was a third bumper option let alone something called a "capable" bumper until I saw a thread on it here.
Mine finally made it to Nashville, 12 days after leaving Michigan. Took me 9 tries to get CSX to understand my car number. You have to be in a soundproof chamber and talk painfully slow before it picks it up. "TTGX" - ERTM, is that correct?
It's not even close with what it picks up.
I was moved a few times, finally got an 11/28 date, built on 11/30 and then the tracker, or an email or something, said it was going through extra quality control, or something along those lines and then finally on 1/3 I got the shipped email. Not sure what that QC thing was about but I'm hoping...
