I've been watching various videos across the web and no it won't drive up Everest, do 6000 miles on a tank of fuel, carry 40 tonnes or fit 60''tyres, but these people are missing the point. That's not what it was designed for. There are plenty of people who like the Grenny for what it is and what it was designed for.
The thing is there is a man in the UK who loves the old Defender and wanted to carry on the no fuss 4x4 type vehicle, he was willing to put his money where his mouth is to cerate what HE wanted.
I watched an interview with Justin Hocevar , very informative (even for us UK residents) skip to 48.43 the reply is spot on.
Everything can be modified for a specific purpose/use, are they haters or just frightened of the unknown????
