What is the service life of a sedan?
2 Answers
The service life of a sedan varies depending on the vehicle's purpose: 1. Non-commercial use: There is no specified service life for sedans. After 15 years of use, the vehicle can continue to be used if it passes inspection, with mandatory bi-annual inspections. After 20 years, from the 21st year onward, the vehicle must undergo quarterly inspections annually. 2. Commercial use: When used as passenger transport, sedans have a service life of only eight years. Here are specific standards regarding vehicle usage: 1. Chassis output power requirements: Strict regulations apply to older vehicles during annual inspections. For private vehicles undergoing power tests, the chassis output power must not be less than 60% of the engine's rated power or 65% of its maximum net power. 2. Scrapping standards: Vehicles that fail safety or emission standards during an inspection cycle will be mandatorily scrapped. Vehicles that fail to obtain a passing inspection mark for three consecutive inspection cycles after their validity period expires will also be forcibly scrapped.
After running this auto repair shop for so many years, I've seen plenty of old cars still running strong. Since the national policy changed, there's no clear usage lifespan restriction for private vehicles - as long as you pass the annual inspection on time, you can keep driving. In reality, a car's longevity mainly depends on how you use and maintain it. Regular oil changes, timely chassis and brake system checks, and avoiding harsh road conditions can easily keep a car running for 15 to 20 years without major issues. Of course, older vehicles require more frequent inspections - cars over 15 years need annual checks, and emission failures can lead to driving restrictions. Recently, I serviced a 1998 vintage Santana that's still running daily highway trips thanks to the owner's meticulous maintenance.
