Experience turbo lag and power surge during road tests; check for significant oil accumulation at the turbo intake and intercooler connections (slight oil vapor is normal); and use OBD to read the real-time boost pressure peak to see if it meets factory settings.

If the car has been maintained at an authorized dealer, we can extract the desensitized official maintenance history (including entry time, mileage, and maintenance items) through a paid third-party data provider and provide it to you. If some year records are missing, we will honestly inform you that the "records are incomplete."

Extremely authoritative. The third-party data service providers we connect to legally access the Chinese Public Security Traffic Management Platform, the insurance claims network directly under the China Banking and Insurance Regulatory Commission, and the after-sales databases of major automotive manufacturers. We perform secondary logical verification based on this underlying data.
