I am looking for info on the build of my 2021 Mach 1, it was built on the first day of the new Mach 1 production and I'd like to know a little more about how it came to be that a RHD Mach 1 destined for New Zealand was assembled on day one.
is there anyone from Ford or the Flat Rock plant on here?

 

You are better off going to the Mustang6G forum.

Ford used to have reps on here but once the S550 came out and that new Forum site was started, the reps only frequent that site. That and most if not all New Gen Mach 1 people online will most likely be part of that site.
