My dealer told me 60-90 days.
You can track your car's build progress on the Dodge Vehicle Order Tracking System (VOTS) site:
https://www.dodge.com/vots/
Keep in mind, though, that this thing will drive you nuts because you'll be checking it every hour and be disappointed every time you see there's no change in status. You'll check it less and less, maybe every few days or so, and then all of a sudden you'll be surprised when the status changes. Mine was in "Production Scheduled" for almost a month. Now it's in Paint, and I've read on here that it takes 3 days to build the car. After that, it's Final Inspection, Shipment, and then Delivery. Most people agree that the VOTS thing isn't really that accurate, but it's just a way to appease us eager customers. It's kind of fun to look at, anyway.
I've heard of cars hanging around in the Final Inspection stage for weeks. Then maybe another couple weeks for shipment. I ordered mine on Jan 8, and I hope to get it sometime in March.
Whereabouts in Texas are you? I have some buddies in Dallas.
