Interesting question. The 21 RT I ordered was built at 6 AM on Friday the 13th. It says so on the build sheet. Now in regards to when a vehicle is built having an effect on quality control, well that’s a crapshoot.
7 day production, 24 hours a day, kind of changes the old adage of ”Built on a Friday”. From what I have read, there are actually more workers on the line at Jefferson North Assembly Plant in Detroit, as they are training for the new Mack Avenue Plant, where the new GC’s will be built. Maybe good, maybe great, maybe time will tell if the rookie forgot something. The main reason production appears to be slower, is the supply chain has hurt the assembly lines efficiency. Lack of Brembos, was a reason apparently for the delay in the Tow n go versions. I would be more concerned about buying a DD or GC built the day after a Detroit Lions game if they lost. 🤔
