Is it necessary to hire a mechanic to inspect the car when buying from a 4S store?

[LeArthur]

You can ask a maintenance mechanic to inspect the vehicle. This method can provide more reassurance that the purchased motor vehicle is brand new, avoiding future usage troubles. The 4S store will not refuse this behavior as it is a very normal inspection process for the motor vehicle. Exterior: Don't rush to get in the car. Walk around it a few times to check if the paint surface is complete, without scratches, and the paint color is consistent. Look at the body curves from a side angle to ensure they are smooth and free of dents. Lights: Make sure to test each light to see if it works properly. Under the hood: Open the engine hood and check for any abnormalities inside, such as various fluids. A little dust is fine. Check if the coolant level is between min and max, and inspect visible pipelines for any wear.
