The damage usually starts with small straight lines of cracks. It later graduates to terrible, ugly lines crossing each other making your dashboard look bad and less appealing. Your front seat is also not spared and will start cracking and peeling off eventually. This makes your car look old and unattractive while reducing its market value in the process!

That is what the scorching sun and terrible heat in Africa can do to a car.
The heat also makes sitting in the car on sunny days unbearable after it has been parked outside for a while as leather materials tend to absorb and hold heat faster than other materials which will cause the interior of the car to also heat up.
