Hi Roach
No offence, but I don't think the Grenadier is a vehicle for someone considering alternatives (With the exception of the G-Wagon, possibly). I think of this is a vehicle you commit to, and keep for many years. This is vehicle for which purchase is just the start of a journey. Older LR Defenders, Jeep, Toyota, etc also have owners wishing to do the same. This is not in my view, a vehicle for accounting. I suspect that most of us on here have purchased this vehicle with no tax incentives and in many cases, with no finance.
By way of encouragement. Here in the UK there is an overland expedition company called ARDventures. The owner is very experienced in this type of vehicle and although an early hand raiser, he cancelled his order and put a vid' on YouTube explaining why he was so disappointed with the Grenadier.
He now owns a Grenadier and loves it. Not exactly sure what won him over but he needed it to fill a specific purpose.
Best of luck in whatever you choose.
PS.
Hope I don't sound condescending but this is not a vehicle I would ever 'recommend'. I would simply tell of my personal experience and admiration of the vehicle.
