The usable lifespan of a car is not determined by its age but by its mileage. The government will recommend scrapping a car once it reaches 600,000 kilometers. Here are some ways to extend your car's lifespan: 1. Maintain good driving habits: The way you drive significantly impacts your car's longevity. Gentle driving, gradual acceleration, and anticipating braking can reduce wear and tear while saving fuel. In cold weather, warm up the car first to allow the lubricant to circulate freely and fully lubricate internal components. 2. Regular cleaning and weight reduction are essential: Take care of the car's exterior with periodic washing and waxing, and don’t neglect the interior. Spend time cleaning instead of just masking odors with air fresheners, and vacuum the carpets regularly. 3. Choose a trusted repair shop: Visiting different shops each time means every technician has to relearn your car, perform the same thorough inspection, identify potential issues, and then address them. This process takes longer and may cost more.

As a homemaker, I believe a car should be considered for replacement after 8 to 10 years of use. Our family's old car has been running for nearly 12 years – it carried our child from kindergarten to middle school, but now the space is insufficient, and the backseat feels cramped. Repair costs keep climbing; just annual brake maintenance and battery replacements cost 4,000-5,000 yuan, whereas monthly payments for a new car would only be 2,000-3,000 yuan – financially, it makes more sense. Safety-wise, older cars have fewer airbags and less sturdy frames, making them prone to shaking on highways; new cars come with better collision prevention systems, giving peace of mind when driving with kids. Additionally, once a car reaches around 150,000 kilometers, fuel and maintenance costs rise significantly. I recommend regularly checking the vehicle's condition – if there are frequent strange noises or oil leaks, start planning for a replacement early rather than waiting for major issues. Over time, it affects daily life too, like slow air conditioning that makes summers unbearable.

From a cost-saving perspective, I believe replacing a car after about 7 years is the most economical. Having owned over a dozen used cars, I've found that new cars depreciate rapidly in the first five years, but maintenance costs double in the subsequent five years. For example, repairing a 10-year-old car's engine might cost over 10,000 yuan, while the down payment for a new car is just tens of thousands. Moreover, in the used car market, 10-year-old vehicles fetch low prices, so it's better to sell them in time to recover some cash. I usually set a budget and evaluate when the car reaches 100,000 kilometers: if annual repair costs exceed 4,000 yuan or insurance premiums rise, I decisively replace it. Rising fuel prices are also a consideration, as older cars have higher fuel consumption, wasting money. Safety is another factor—older cars have weaker brakes, making them dangerous in rainy conditions. Replacing the car earlier also allows you to take advantage of favorable loan offers.

I prioritize environmental protection, and believe cars should be replaced after 6 years. Older vehicles exceed emission standards, consume 20%-30% more fuel than new cars, and cause severe pollution. When I drove an old car, the exhaust fumes were strong, but after switching to a new energy vehicle, it became quiet and fuel-efficient. Maintaining old cars wastes resources, such as frequent oil changes that increase environmental burdens. New car technologies are constantly advancing, with electrification being more low-carbon. Insisting on driving a car for over 10 years is not eco-friendly. I recommend taking action at 50,000 kilometers or 5 years to reduce your carbon footprint while enjoying modern technology.
