Probably your first car's vehicle type
A sedan, or saloon, is a passenger car designed for urban drivers to transport passengers, and their belongings on normal roads. With its lower center of gravity compare to other types like SUV, it has lower percentage of chance to roll over in case of an accident.
This is probably the first type of vehicle you've driven when you got your first driver's license. It is the easiest type to drive and cheapest to buy.
Due sedan's low ground clearance, its driving capability is limited to normal roads, and no bumps on high speed. It is not recommend to drive sedan on off-road or tow something that's heavy, because it will not have enough traction to move the payload.
