I've been on the fence since the pre-production days and finally got around to test-driving one this past week. The steer-by-wire does take some time to adjust, but not huge. However, despite SIr Jim's original design ethos of building a purpose-built vehicle along the lines of the old Defender, the amount of electronics the Grenny has is concerning to me. I suppose that's unavoidable today.
This thread has been informative, but, if anything, it may be pushing me to the side of buying an old Defender 110 and resto-modding it over buying a more 'modern' vehicle. The other thing that's clear for my situation is that I can't daily drive a Gren, as my daily has to be a low ground clearance vehicle, so the Gren would be like my Range Rover Classic, for going off-road.
I do hope the IG succeeds, but I guess only time will tell.
