A PDI (Pre-Delivery Inspection) is a final check completed before the sale of a vehicle, whether brand new or pre-owned. The purpose of a PDI is to ensure that the vehicle is in top mechanical and operational condition, and meets the manufacturers standards. The inspection is usually carried out by the dealer, and it involves examining the car top to bottom, including the paintwork, interior, and engine, to check for any defects that may have been missed during the manufacturing process. The exact procedure varies depending on the manufacturer, but PDI checks generally examine the major components of the car, such as the wheels, exterior lights, brakes, and engine oil level and quality. The PDI process helps to detect any issues that might have been missed during manufacturing or transportation, eliminating any problems to the car that could concern the customer. The benefits of a PDI include preventing the need for future repairs by detecting any issues, ensuring that the customer receives a new vehicle that is problem-free, and enhancing the overall customer experience.
