What is the purpose of the Reference number field?

Explanation:
The Reference number field serves as a unique identifier used to index and locate a specific entry in the dataset. It helps you quickly retrieve the exact record and keeps the data organized, especially when combining information from different sources. It isn’t describing the car itself (like engine size or color), and it isn’t the vehicle’s VIN, which is the real-world identifier for a car.
