Car Rental and Sightseeing in Kazakhstan

[Hartum]

My wife and I make it a point to hit a new country every single year to keep things fresh. We have seen some wild spots like the temples in Myanmar, the dunes in Namibia, and the high plains of Bolivia, so we have been around the block a few times. This year we are locked in on Kazakhstan since the landscapes there look absolutely massive and diverse. We definitely need a solid 4x4 with serious ground clearance to handle the terrain. Any leads on where to find a tough vehicle for the trip, and what spots should we put at the top of our list to see?
