Congrats. Give us some real world feedback.
I'm really happy with it so far. It has a very commanding feel on the road, surefooted and solid. No rattles. Steering took getting used to, but I'm now 280 miles in and no longer an issue. Doors are heavy like a vault. I expect to get 17-18mpg in regular mixed driving. Got 15mpg with my first tank on winter blend in the NE. My LC gets 13mpg today with 175k miles on it. I love the way it looks. G wagons look plain Jane to me now and look oddly proportioned especially next to the Grenadier.
In terms of some things I would change if I had a magic wand:
ADAS (advanced driver assist system) comes loaded on the vehicle. Lane departure is fine, but speed overage indication is quite annoying. Have to turn off every time I start a new drive but a software fix from the factory is on the way. Supposedly has some kind of drowsy driver detection, but not sure how it works.
Memory seats. I wish I had them. These seats are super comfortable Recaro's but they are manually adjusted.
Some kind of retractable shade for the Safari windows would have been nice. The tint is nice and dark and so far doesn't bother me, but I can see it bothering some. Would be nice to have an option especially in the summer perhaps. But the headroom is awesome (high ceiling) and it just feels much more open and airy than the LC. Safari windows add to that feel.
Second row adjustable backrest would have been nice. But not too many vehicles have them. I'm just comparing to the LC.
Engine is a bit noisier than the LC. I can hear/feel it at a red light, and I think there might be some highway exhaust drone at 65-70mph. Monitoring that. Hoping it will dissipate as the engine breaks in. Never had this issue in the LC obviously.
That's all I have to share for now. Thanks for asking.
