APP generally provides completely authentic records for queries. Specific situations: Some records might not be displayed, so the query results can only serve as a reference. Visual inspection and instruments are still needed to verify the results. If the car has always been maintained and repaired at a 4S shop, you can check the records in the 4S shop's system. Or if the car has always been serviced at a fixed repair shop, you can check the records there. records from any region can be found. Insurance claim status can be checked with the insurance company, but maintenance and repair records not done at a 4S shop cannot be found. Vehicle maintenance records: This refers to an industry document that collects data involving the vehicle's own historical information, including maintenance records, service records, accident records, insurance records, theft records, etc., systematically organizes and analyzes them, and presents them in written form to the party requesting the query.

I think the accuracy of Che300's record queries varies from person to person. I've used it several times myself and found the data quite reliable most of the time—it quickly reveals a vehicle's repair and accident history, especially for records covered by authorized 4S shops. However, the issue is that some smaller repair shops may not fully upload or delay their records, leading to omissions. For example, when I helped a friend check a used car, Che300 showed a clean record, but later during the test drive, we discovered hidden engine issues. My advice is to use this tool as a preliminary reference only—don’t rely on it entirely. It’s best to cross-check by directly querying the manufacturer with the vehicle’s VIN for an authentic report or spend some money on a professional inspection. Overall, it’s a convenient entry point that saves time and money, but its accuracy heavily depends on data sources, so always maintain a bit of skepticism.

As someone who frequently buys and sells cars, I pay close attention to the reliability of records. Che300 is convenient and quick to use, with affordable fees, and it's very helpful for checking basic maintenance information. However, its accuracy isn't 100%, especially for older cars or maintenance records from different regions, where errors are more likely. Once, I avoided buying a problematic car thanks to it, as I found out about an accident history; but in another case, it showed no records at all, even though the car had been serviced multiple times. To boost confidence, you can use it alongside the official app or an on-site inspection. The key is not to skip the inspection steps—spending a few dozen bucks for peace of mind is worth it. I usually advise my friends to use it for initial screening and then conduct a physical test to avoid being misled by fake reports.

After being in the car repair business for a long time, I've noticed that Che300's data sources are inconsistent. It integrates records from numerous 4S shops and centers, generally providing higher accuracy for newer car models. However, records from small workshops or private repairs are often missing, and even system updates can be slow, leading to misleading information. I've helped clients check several times, with results being hit or miss—especially for older vehicles with more issues. If you want to buy a reliable car, don't just rely on online tools. Keep your eyes open, inspect the car yourself, and verify the original factory reports. This can save you from unexpected repair costs down the line.

Young people prefer using apps for car-related matters. Che300 is straightforward to operate, generating reports with just a few clicks. I've tried checking records multiple times, and most of the data is reliable, saving me the hassle of running around. However, data synchronization issues are common, such as inaccurate records for older or modified cars, leading to occasional false reports. Don't be too naive when using it; it's better to verify with the vehicle manual or a friend's experience. While technology offers convenience, reliability requires manual reinforcement.

Considering the potential risks of used cars, I approach Che300's accuracy with caution. It offers a quick service for querying records, with generally precise data, but it's not comprehensive and may miss minor accidents. A friend of mine once trusted a clean report, only to later discover hidden repair spots. I advise car owners not to rely solely on it for decision-making; additional checks like reviewing the vehicle's maintenance manual and conducting physical tests are necessary to avoid hefty repair bills. Such tools help save money and time, but trust needs to be built over time.
