Seek independent third-party vehicle inspection institutions with nationwide chains for more reliable results. Below are methods to check if a used car has been in an accident: 1. Check the glass production date: Normally, glass isn't replaced, so checking its production date can be telling. The date is usually in a format of numbers + dots, where numbers represent the year and dots represent the month. 2. Examine the wear on the frame: If the car has been in a major accident, the body frame will show varying degrees of dents and misalignment, so assessing the frame's condition can indicate past accidents. 3. Inspect the screws: Look at the screws on the hood, radiator support, and door connections. If any of these screws show abnormalities, it's a strong indication the car was in a major accident. 4. Review maintenance records: Check the maintenance records at authorized dealerships (4S shops). Any accident repairs done at a 4S shop will be systematically recorded.

Last time I helped a friend pick a used car, I did a lot of homework. Choosing the right inspection agency is crucial. Third-party professional companies like Guazi Used Car Inspection have technical teams that provide on-site services, checking core components such as the engine, chassis, and brake pads. They can also check for accident history and water damage traces. A report costs a few hundred yuan but helps avoid major pitfalls. Some dealerships provide self-inspection reports, but you need to watch out for tricks, such as misrepresenting the car's condition. 4S shops are also reliable, especially for specific brands, as their technicians are very familiar with the vehicles, but the cost might be higher. I recommend opting for independent inspections first—online booking is very convenient. Don’t skip this step out of laziness. After all, paying a bit more for a used car is fine, but ending up with a car that needs constant repairs is a nightmare. Also, check the qualifications and reputation of the inspection agency. Reading user reviews can help you avoid detours. Overall, professional inspections provide ample information, giving you peace of mind.

As a parent who frequently travels with children, I believe safety should be the top priority when inspecting a used car. For inspection services, I recommend brand-authorized 4S dealerships or certified institutions like third-party platforms such as Cha Boss. Technicians at 4S stores have in-depth knowledge of original factory components and can thoroughly examine the braking system, suspension, and airbags, even retrieving maintenance records to check for collision history. Third-party inspectors offer more neutral evaluations, conducting comprehensive tests on engine performance and electrical issues to avoid purchasing vehicles with hidden oil leaks. Although the cost may be a few hundred yuan, it is far lower than the repair expenses for an accident-damaged car. I also remind my family not to skip inspections to save money—dealership self-inspection reports are easy to obtain but lack depth, making them prone to deception. Regularly following discussions on used car market forums about common pitfalls also helps in early prevention. Safe driving starts with a good car, and timely inspections protect the whole family.

With years of experience in cars, I often help friends check used vehicles. There are only a few reliable inspection agencies: independent third parties like the Car e-Gu team offer professional on-site services, thoroughly examining the car's frame, chassis wear, and electronic faults, providing more impartial assessments than dealerships. Dealership inspections are free and simple but may overlook issues, offering only basic exterior reports. Mobile app-based inspections are economical and convenient—just choose a certified platform. Remember, the key is to check accident history and critical component conditions. Don't skimp on inspection fees; a small investment ensures peace of mind.
