That doesn't look like a Kalahari to me. If you look under the hood, it appears to have been a white Discovery that was poorly repainted. The Kalaharis I have seen had grey two-tone interior, but that one looks beige. they also didn't have armrests. A Kalahari should also have a Saudi spec grill. Figures the ExPo crowd would be all about it.
Good catch... I hadn't looked at it in detail, and finding an example of a grey Kalahari is difficult. That'll teach me to post without verifying!
