What does the low-end version mean?

[GideonFitz]

Low-end version means simplified configuration, without features like leather seats, power windows, and lacking many electronic and electrical control functions, indicating a lower level of equipment. Standard version includes all the normal electric controls, such as power windows, power steering, air conditioning, etc. The mid-range version is slightly more advanced than the standard version, not only including all the functions of the standard version but also possibly adding features like more airbags, sunroof, leather seats, power seats, seat heating, etc. The high-end version is the top configuration, with higher equipment, and can be considered the flagship model of this car series. Differences can be seen in appearance, such as wheels, tires, logos, etc., and it may also include many more electronic controls like suspension, navigation, onboard computer, panoramic sunroof, EPS, etc.
