It’s my understanding that once the Refresh starts production then the LTD stops. If this is an LTD then I don’t get the 4 – 5 months. If you have your sales order code you can “chat” with a rep online just go to chevrolet.com and look for customer support. Once you connect with someone provide that code and they can tell you if the order has been accepted and the anticipated production date. For instance I ordered my Refresh (High Country) around mid Jan, I was told by both the dealer and doing the chat the scheduled build date is the week of 2/28. Because dates have been known to slip with GM I will be following up with both this week and every week until I actually have the vehicle. Good luck to you, but I think I would ask a few more questions.
