I think the dealers cars on order show up automatically once a vin is issued and most of them are spoken for already. You need to call dealer to see. Had that problem in 2020 when trying to find a new GT500.
Why did you not take more pictures? Did you see the license plate, was it a manufacture plate? I live in a suburb of Detroit and have not seen one yet.
Mine is just a GT, but with PP. my 2020 GT 500 waited 1 yr for it but it sat at the plant during covid shutdown for 3 months. This car I am going to use for an everyday driver so I need it asap, just made my last lease payment on my car that I drive everyday now.
