Be hard to take it 4wding up a bush track, or spotlighting 'roos and foxes!!!!
When 4wding or considering a purchase of one always go with the masses, that way skills, knowledge, spares, and aftermarket support is on your side when stuck in Broome!!!
I'd hate to smack a 'roo or even a sparrow in that Bentley, hands would be in pocket dragging out dollars you don't have for a repair you wouldn't be happy with.
But if you don't intend getting past Penrith and you think a driveway is a dirt road then save your $$$ and buy a Honda Oddyssey.
