What does a commercial version of a car mean?

[StHenry]

Commercial vehicles refer to vehicles that have been approved by the competent authorities by the end of the reporting period and are eligible to participate in commercial operations. This includes vehicles that are technically sound, under repair, awaiting repair, long-term parked, and those intended for scrapping but not yet approved by the higher authorities. However, it does not include non-commercial vehicles of the enterprise (such as cable cars, tankers, trucks) or borrowed passenger vehicles. Cars generally come in standard, low, mid, and high-end versions, which respectively refer to: 1. Low-end: Generally simplified configuration, without leather seats or power windows, lacking many electronic control functions; 2. Standard: Includes normal electric controls such as power windows, power steering, air conditioning, etc.; 3. Mid-range: Slightly more advanced than standard, not only including all standard features but also possibly adding airbags, sunroof, leather seats, power seats, seat heating, etc.; 4. High-end: Higher than all the above configurations, can also be considered the flagship version of the model.
