I have driven one off-road and been a passenger on the 2B tour. It's like my old (sold) LR110CSW, but bigger, rides at least as well as a P38, has twice the power of my LR, very much quieter, good air con, comfortable seats, controls like an old aeroplane, (big, physical switches - you need to learn their positions as they are not especially ergonomic), relaxing to drive and reassuringly solid.
If the hype is to be believed, it should be capable of being maintained in the field by owner/drivers using a readily available electronic manual and parts book, or you can use a local dealer.
I've ordered one; I want a long lasting vehicle I can maintain outside of a dealer network that was designed recently and can tow my classic cars on a motorsport trailer. I have not met many people who want one, but those who do, are really keen. Locally, there is one man who uses the same agricultural engineers I do, has ordered the full spec launch edition, Trailmaster; he'll use it for his farm work, keepering and towing a stock trailer. His Grenadier will be about £66k OTR; he looked at the LR products but the availability is low for cheap vehicles and the more expensive ones are really expensive!
