Summary

Used cars are popular these days, especially for new drivers who have just obtained their licenses, who often buy a used car as a transitional vehicle. Used cars offer better value for money, and used cars around five years old, even some "nearly new" cars, are particularly popular among consumers. However, how should owners maintain used cars of different ages? Yitongda explains the five stages of a car's life cycle, advising owners to take appropriate maintenance measures based on the stage of their car's lifespan.

Young (1-3 years): Routine maintenance is sufficient
Used cars between one and two years old are generally referred to as "nearly new." These vehicles are in excellent condition and have a well-maintained exterior, which is a key reason for their popularity among younger used cars. Therefore, with routine maintenance, these used cars are generally safe.
Mature (3-5 years): Replace parts as needed
Used cars aged 3-5 years are a good value for both buying and selling. For buyers, the overall condition of a 3-year-old car is generally good, allowing them to be found at a lower price. For sellers, however, the warranty period is typically over, and some parts need replacement, increasing maintenance costs. This is when it's most cost-effective to trade in the car.
Cars aged 3-5 years require regular inspection and appropriate replacement of certain components. For brake pads, in addition to checking the remaining thickness, check the wear of the shoe, ensuring uniform wear on both sides, and ensure smooth return. Any abnormalities must be addressed immediately. Shock absorbers should also be carefully maintained. Shock absorbers typically experience some oil leakage, but excessive leakage warrants attention, as it will accelerate wear of the shock absorber studs and reduce the vehicle's service life.

5-8 Years: Replace when necessary to maintain performance
After 5-8 years, a car enters its "middle age" and is prone to minor problems. However, if the owner maintains it well, these aging issues will occur later. Also, be sure to clean and replace the filter regularly; a small investment can save you significant money and provide greater driving safety. Also, the water tank will corrode after about 6 years of use due to chemicals inside, and some vehicles may even start leaking, requiring prompt replacement.
8-10 Years: The Old Age Stage: Requires Careful Care.
At this stage, the vehicle gradually enters its maintenance phase. Minor parts replaced in the third and fourth years are almost due for replacement. Additionally, most automatic transmission vehicles should also have their automatic transmission serviced at this time. This is when meticulous care is even more crucial. In addition to scheduling oil changes ahead of schedule, try to minimize engine revs.

Over 10 Years: The "Critical" Stage: Regular and comprehensive inspections.
Older vehicles over 10 years old often command significantly lower prices, allowing you to purchase one for only one-tenth of the original price or even less. However, these vehicles often have excessive mileage, resulting in significant wear and tear on key components like the engine and transmission, shortening the vehicle's overall service life. It's recommended that used vehicles over 10 years old undergo regular inspections at a repair shop.
