You just have to be patient. I placed my order for a 2SS on Sept 22. I'm #1 priority at my dealership, so the next 2SS allocation they get is mine. It could be this week or it could be next month, there's no telling. My salesman said based off how they have been getting allocations to expect an allocation this month (November).
If you look around forums and online, you'll find that typical wait times from when the order is placed to delivery is 4-6 months. The longer wait times seem to be for the 2SS/1LEs and ZL1s.
Patience is the key. With the rumor that the Camaro is surviving for a 2024 model year, I wouldn't stress it. If all else fails, there's always the 7th gen Mustang. Right?
If you're not the patient type, you might want to try to find in transit that meets your needs.
