The general method and principles for inspecting a new car are: from far to near, from outside to inside, from top to bottom, from static to dynamic, checking item by item without missing anything. Check the car's documents and chassis number. The main documents for a new car include the vehicle certificate of conformity, user manual, warranty manual, etc. Verify that the VIN code and engine number on the certificate match those on the car, and check that the stamped numbers are neat and show no signs of alteration. There is a VIN code on the lower left side of the windshield; the tenth digit indicates the car's production year. The production date is also marked on the car's nameplate, and these dates should match or be close to the date on the certificate of conformity. A significant discrepancy indicates a problem. Check if the car is level. Measure the distance between the wheels and the wheel arches. Generally, the distance should be the same for wheels on the same axle (front wheels compared to front wheels, rear wheels compared to rear wheels). A large discrepancy suggests an issue with the suspension system. Inspect the paint quality. Examine the paint under sunlight from various angles to assess its smoothness and color consistency. For metallic or pearl paints, check the uniformity of the aluminum or mica particles in the paint. Inspect the gaps between structural components. Gaps around the hood, doors, bumpers, trunk, door seams, and front/rear lights should be small, even, and symmetrical. Check the car's glass. Ensure all glass panels are smooth and clear. The windshield must be particularly flat, with no distortion when viewing external objects from any angle. Verify that the glass is original. There is a label beneath the glass consisting of symbols, numbers, and letters, which includes information such as the manufacturer, glass brand, certification, type, and production date. Make sure the production dates of all glass panels are consistent. Inspect the car's tires. New tires should have undamaged sidewalls and no punctures on the tread. The tread should show visible tire hairs on all four tires. If the tires are completely smooth with no hairs, consider whether the car has been subjected to rough driving. The production date is marked on the tire sidewall; all four tires should have the same production date. Inconsistencies indicate tire replacements. Check the battery. The battery status indicator shows its condition: green indicates good charge and condition, while black or white suggests low charge or damage. Inspect the interior. Ensure the seats are secure and adjust properly in all directions. Check for damage to the seat fabric; for leather seats, look for cracks. Examine the dashboard and door panels for wear or damage. The headliner should be clean and neat, and the floor should show no water stains or odors.
