I'm not really a fan of the concept. The biggest draw of a proper land rover to me is the simplicity and adaptability. The new one might be technically incredible, but if I can't take it to bits and see how it works then I'm just not interested.
Thing is, land rover don't care what I think. No matter what they had brought out, I was never going to buy a new one anyway. If I had £40k going spare I'd go on holiday for a year, not buy a car!
They'll probably sell loads of them, though I can't help but wonder if they will be taking sales from other areas in their own product range. It doesn't seem utilitarian enough to occupy a different niche from the likes of the Discovery. In fact, if it was called a Discovery I could probably understand it a bit better.
I can't see the local farmers taking one on instead of the near-ubiquitous Ford Ranger either. The Ranger starts at half the price of the Defender. Incidentally, I went to check the price of the Ranger and it's listed without VAT, where the Defender is listed including VAT. Even the advertised pricing shows who is really expected to buy the new Defender!
