What's South Sudan's president's ride?

A few of you may remember my Rides of Heads of State Series.  Through a lot of detective work, I figured out and catalogued the cars of every world leader.*

Well, very soon, we're going to have a new country-- South Sudan.  You may have already seen its president, Salva Kiir Mayardit, a.k.a. the dude with the black cowboy hat.  So what's his ride?  In a country the size of France, it only has 50 km of paved roads.  So of course, he has a Land Cruiser.

This is the only picture I could find of the president in a car.  So I had to use my sleuthing skills to identify the make and model of the vehicle.

Here is a picture of a Land Cruiser's interior for comparison.  Note the shapes of the windows, locations of the hand grips, and locations of the vents next to said grips.

Here is the (revised) final tally:
