The center of gravity of a vehicle depends on all three weight distributions. Technically, it is the point where all the weight could be concentrated for purposes of calculating vehicle performance. More practically, it is an indication of how well the weight is distributed. Of the three weight distributions, the location of the center of gravity in the vertical direction is the most important because it affects stability - high is bad, low is good.
How do you find centre of gravity of a vehicle?
The higher the center of gravity the easier it is to roll over.
Yes . If the center of pressure, for the vehicle as a whole, is not located behind the center of gravity (away from the direction of the flight path), then the vehicle will have unstable motion and can tumble. Adding fins to the rear of the vehicle (or increasing fin surface area) will move the center of pressure aft, affording stable flight. A similar effect can be produced by adding weight to the front of the vehicle.
To lower the center of gravity to improve handling and reduce the possibility of a roll over.
Should be about half way at the "belt-line"
It is best to keep the center of gravity low on any road vehicle. This can be done by design, and by loading the heaviest items lowest with lighter items higher up. So to answer your question, they need as low a center of gravity as is physically possible.
It'll become more prone to sway and topple over when cornering.

To reduce the centre of gravity and improve stability of the vehicle.
The center of gravity is an average of the location of the points of gravity. If you had a flying ring like a Frisbee but without the center, the center of the gravity would be in the hole.
Carrying heavy items can indeed cause an increase in a car's center of gravity. This is particularly true for SUVs, which typically have a higher center of gravity to begin with. To keep the center of gravity as low as possible, load heavy items as low in the chassis as possible, and towards the center of the vehicle. Heavy items should never be carried on a roof or luggage rack.
