Methods to determine if it's a new car: 1. Check the production date: If it's quite old, the car might be a stock vehicle; 2. Inspect the engine compartment: Open the engine compartment and check the cleanliness level; 3. Examine the exhaust pipe: Insert a finger into the exhaust pipe to see if it's blackened, which indicates the car has been driven a certain mileage; 4. Check the tires: New tires usually have computer lines like paint, and there will be tire hairs on the side, which wear off after 50 to 100 kilometers. If the tire hairs are completely worn, the car's mileage is abnormal; 5. Listen to the engine sound to see if it's deep, if there are any abnormal noises, and if the vibration is significant.

I often help friends check cars at dealerships, and I think there are several ways to determine if a car is new. First is the exterior inspection: a new car’s paint should be even and glossy, with no scratches or touch-up marks, especially when checking for consistent reflections under sunlight. The tire treads should be deep and unworn, and the rims should be clean without brake dust. For the interior, leather or fabric seats should be fresh and soft, and the car should have a new plastic smell—no stale cigarette odors or perfume masking scents. Also, check the odometer; new cars typically have under 50 km on them at delivery—anything more might indicate a display or test-drive vehicle. Documentation and labels are important too: the VIN should be clearly visible, and the manufacturing date should be within three months of purchase to avoid old inventory. Finally, start the engine and listen—a new car runs smoothly with no odd noises, and gear shifts should be seamless. An untouched car always has a certain freshness to it, and considering all these factors together gives a reliable assessment.

As an ordinary car owner, I figured this out when buying my first car. For a new car, pay attention to details: when you open the engine bay, all components should be clean and shiny, free from oil stains or dust, with no rust on battery terminals. The seat protective films are usually still in place, and seat belts show no wear or stains. During the test drive, the steering wheel should feel neither too loose nor too tight, brakes should respond promptly without strange noises. The interior screens and buttons should look brand new, with the system booting up quickly without lag. Don't forget to smell the air vents - a new car should have that authentic new car smell, not mixed with odd odors. Mileage should be under 100 km, the manual's packaging unopened, and keys unused and unprogrammed. Check the manufacturing date to ensure it's fresh stock, not warehouse leftovers. These visual checks can save you a lot of hassle.

When I usually repair cars, I'll tell you how to identify a new car. Check the engine oil condition—new car oil is clear and bright, not cloudy, unlike the black and dirty oil in old cars. The chassis and suspension components show no signs of rust or wear. When starting the car, connect an OBD scanner to check for short vehicle operation time and no error codes. The tire pressure should be sufficient, and the brake discs should have no wear marks. The interior plastic parts should be smooth and free of scratches, the audio system should respond quickly without adjustments, and the factory labels should be clear and intact to avoid suspicion of refurbishment.

Our family frequently changes cars, and I evaluate new cars from a practical perspective. The doors should open and close smoothly without noise, the wiper blades should show no signs of aging or cracks, and the headlights should provide uniform illumination without dimming or yellowing. The interior carpets should lie flat without indentations, and the child seat anchors should be free of rust. The air conditioning should cool quickly without strange odors, and the filters should be newly replaced. Safety systems like the rearview camera should display clear images with responsive alerts. When inspecting the trunk, the spare tire should have deep treads and show no signs of use, and the tool kit should remain unopened. The manufacturing date should be within the last six months, confirming it's a fresh model.
