Car Analytics is a service that offers a free vehicle history check. Enter the vehicle's registration number or its vehicle identification number (VIN) to get a report that includes important information about the vehicle's history. This can include details about its previous owners, outstanding finance, mileage discrepancies, and more. Keep in mind that while these reports can provide valuable information, they might have a partial history of the vehicle. It's still recommended to have a professional mechanic inspect any used vehicle before making a purchase.
