Used cars with 60,000 to 100,000 kilometers and 3-5 years old are the most suitable. Below are some precautions for buying and selling used cars: 1. Check the Vehicle License: Verify if the patterns on the front and back pages of the vehicle license match when combined. Check if the license photo and chassis number correspond with the vehicle. 2. Check the Vehicle Insurance: Confirm if the chassis number and engine number on the insurance policy match those on the vehicle license and if the insurance is still valid. 3. Check the Vehicle Registration Certificate: Ensure the font on the vehicle registration certificate matches the vehicle license. Verify if the chassis number and engine number are the same as on the vehicle license. Check if the manufacturing date and registration date align with the dealer's description. Look for frequent transfers in the registration records within a short period.

I find this question quite interesting. There really isn't a rigid standard for what constitutes appropriate mileage for a used car—it all depends on the overall vehicle condition. As someone who enjoys hunting for used cars, I've seen many examples: a five-year-old Japanese car with around 80,000 kilometers on the odometer can actually be more durable than lower-mileage vehicles if it has complete maintenance records, regular oil changes, new tires, and limited highway use, because the engine is well broken-in. However, if a car is both old and has over 100,000 kilometers, wear and tear will definitely be more significant, potentially causing issues with the steering system or suspension. The key is to test-drive it—check if the gear shifts smoothly, brakes respond well, and whether there are strong odors inside. These factors are far more reliable indicators than just focusing on the mileage number. In short, don't be tempted by cheap, high-mileage old cars. Prioritize vehicles with annual mileage below 15,000 kilometers and make your judgment based on maintenance history—that's the smart approach.

As someone who frequently helps friends choose cars, I believe mileage should be considered alongside budget and usage. If you're tight on budget, an economical model like a Toyota Corolla with 100,000 kilometers can be a good buy as long as the frame isn't rusted and maintenance records are complete. With a lower price and no major engine issues, it can still run well for several years. However, high-mileage vehicles tend to have faster wear on the drivetrain, requiring more frequent part replacements, which can lead to soaring maintenance costs later—potentially costing you more in the long run. For city driving, high mileage is normal, and fewer highway miles are actually better. For cars used extensively in rural areas, be cautious about potential chassis damage. Remember, don't just rely on the odometer—check maintenance reports or third-party inspections to ensure the mileage hasn't been tampered with. This can save you a lot of hassle.

From a mechanical perspective, I believe the appropriate mileage should align with the vehicle's age: around 10,000 kilometers per year is considered ideal, resulting in minimal engine wear and extended lifespan. However, engine designs vary significantly. For instance, German cars with their precision engineering often experience turbocharger failures after 80,000 kilometers, accompanied by high maintenance costs, whereas Korean cars may remain stable even after 120,000 kilometers. The key lies in inspecting critical components like piston rings and valve seals—these parts tend to develop oil leaks or burning issues at high mileages and must be checked proactively. Additionally, don't be overly optimistic about older used cars with low mileage—rubber seals degrade quickly, and clogged fuel lines can still lead to breakdowns. It's advisable to prioritize vehicles within five years old for a balanced data assessment.
