Water damage is one of the most common hidden problems in used cars, and it often escapes basic photo reviews. During a live video inspection, ask the inspector to check these specific points: 1. Smell test: A musty or moldy odor inside the cabin is the first red flag. Have them open all doors, run the AC briefly, and smell the air from the vents—musty AC often indicates water in the HVAC system. 2. Under the carpets: Lift the floor mats and look for water lines, rust stains, or dampness on the carpet backing and the metal floor underneath. Sediment or silt residue is a giveaway. 3. Seat rails and bolts: Pull the seats fully forward and backward. Rust on seat rails or fresh-looking bolts suggests the seats were removed for cleaning after flooding. 4. Trunk area: Check the spare tire well and under the trunk carpet for standing water marks or rust. 5. Electronics: Test every window, seat adjustment, and the infotainment screen—water-damaged electronics behave erratically. Also request a scan report: flood cars often store history codes for multiple control modules that failed simultaneously. Cross-check the car's origin; vehicles from flood-prone southern regions deserve extra scrutiny.

The registration certificate will show whether the previous owner was an individual (registered with ID) or a company (registered with a business license). Vehicles under a company may be driven by multiple people, so we will focus on checking the uniformity of interior wear and the condition of the chassis.

Chinese passenger cars produced after 2005 have fully transitioned to asbestos-free brake pads, clutch plates, and gaskets. However, for export to countries with strict regulations, buyers must pay for sampling and testing by a NATA-accredited laboratory before shipment, and obtain an asbestos-free certificate.
