Ah, yes. Well, I mis-spoke. It depends which one you mean, however. There is the Toyota Hilux (Americans think Libya and Afghanistan when they see pictures of it, because people alwyas mount machine guns on them; I wanted one when first arriving in a certain neighboring country and was unable to find any used ones, as rumor has it said country was supporting Libyan rebels and was buying them in large quantities to ship there).
The other one, which is not good for your plus one, because that is all you can fit, is the Land Cruiser LX pickup truck, also referred to as the Abou Houdh (ابو حوض), the "one with the basin/bathtub" for rough translation. This is super popular everywhere, but specifically amongst Bedouins and the working classes. Why the Bedouins? As you probably saw this thing has pickup and is famed for its ability to go up large sand dunes in reverse (Youtube can show you).
If you like the Land Cruiser LX pick up, there is always the "capsoola", the capsule. Same car, but in a two-door Jeep Wrangler form-factor. This is one of my favorites. It is popular elsewhere because it really flies over sand dunes.
Granted this is not Green Arabia knowledge, but I thought it might be fun for some.
I may or may not have heard how people buy these cars in GCC countries and drive them through Oman and onward to sell in the black market for crazy prices in Yemen. This is one of many fun things I have heard about the black market in Yemen.
Since you generate a lot of interest with this stuff on HN (but you write better), maybe I will start writing this stuff.
