A glimmer of hope and maybe a positive data point for others to reinforce the notion that IA is trying to get Grenadiers delivered by Christmas.
I just called Cory at Warner (my dealer) and he said he got an email last night showing that he's getting (sorry I forgot the exact number, in my excitement) 12? 17? Grenadiers delivered to him in the next week to ten days. He verified that my VIN is on the list. So, maybe I'll have a Grenadier under my Christmas tree that isn't a 1:18 scale model.
ETA: Tow package disabled / temporarily removed, pending software update, maybe available by New Year's. Will have to get it fixed later.
