wait for production to be scheduled. wait for that date to come. Have it built - may be built 100%, may be missing parts. Will sit in transport for months. Then may catch a ride.
Mine was built this summer.... still waiting to take a ride on a train to the midwest.
you'd think GM would at least try to be consistent with their delivery/transport timeframes because even though there may be shortages of trucks/drivers, someone shouldn't be waiting months for a vehicle to be delivered while other vehicles are shipped with almost zero turn around time. Our 23 tahoe was ordered/accepted/built/delivered in a total time of 4 weeks.
depending on where you're located relative to Dallas, will probably play a siginficant factor in your delivery timeframe. Order accepted today will probably have a TPW of mid-Jan so optimistic view would be delivery anywhere from late-Jan to mid Feb. Pessimistic view would be hoping it gets here be spring break.
TPW is your biggest concern right now
