Having been a passenger in two of Joshs' they're not bad to be a passenger in, and can easily keep up with most things
Worlds apart from the Defender... (clearly no bad thing) 
They are a very nice place to be.
I've been lucky enough to drive a few of the ones he's had

I have this weird split personality with Range Rovers. The petrol ones, particularly that supercharged one he had 2 or 3 years ago, I drove it like a man possessed, and had to distract young joshwyatt away from the car when I handed keys back, so the brakes could stop smoking before he looked. Yet that TD6 one he briefly had, I was content just tootling around in it, like a model citizen. The other V8 petrols probably fit somewhere in between from a hooligan perspective.
I really fancy trying a TDV8 one. Powerful enough to keep up, economical enough (when not hoofing it) to be viable for me. On paper anyway.
