How to check a new car when buying

Check the interior. Make sure the interior is clean, pay special attention to seat upholstery (cloth, vinyl or leather, covering driver and passenger seats), interior roof upholstery, door panels and flooring. Make sure there are no stains, cuts, tears, or any other signs of damage to the interior.
Make sure that all electrical and mechanical devices are working properly. Inspect the horn, windshield wipers, air conditioning and heating, power windows and door controller, lights, radios, headlights and seat belts.
Rate the appearance of the vehicle. Go around the car from all sides and carefully study the body and the quality of painting. Make sure there are no dents or scratches on the car. You must also ensure that the tires are in excellent condition. Since you are buying a new car, the tires should not be worn or damaged.
Check the level of fluids and make sure that there is enough (brake fluid, engine coolant, transmission fluid, engine oil, steering fluid and windshield wiper solution). Next, make sure the battery, hoses and belts are in good condition. The upper part of the battery surface should be clean and dry, and the terminal connections must be tight and reliable. Belts and hoses should look new, without any cracks.
Take the car for a test drive. Before you sign a contract, you must make sure that the car is in excellent working condition. Immediately let the seller know if you notice any unusual sounds or noises coming from the car.
