Does that mean any MINI manufactured after January will be a 2022 or any MINI ordered after January won't be built until after the model-year changeover?Yes - my salesman said 2022 starts Feb 1st.
Last year, the factory began manufacturing 2021 models when the factory shut-down ended in May. I would be surprised if 2022 production is starting in 12 days because MINI hasn't yet shown the new front fascia and there aren't even any good spy photos (I don't count the partially obscured spy photo on the Motoring File website as a good spy photo). At this point, we don't even know if the SE will still have its own unique aerodynamic grille.
