Rumor has it that production for the 2021 GT500's will end at the end of Nov. If you have a 2021 GT500 on order and it is not in production, contact your dealer and have him check the new scheduled build date, if it is later than the end of Nov, your order may be canceled. Keep in mind that this is the scheduled end date, so the date could change for the better or possibly worse. The chip shortage, possible supply shortages and cold weather could negatively impact scheduling.
