BMW Certified Pre-Owned vehicles promise that every BMW Certified Pre-Owned vehicle undergoes rigorous quality inspection and restoration. From the proper functioning of the engine and transmission to details such as tire tread thickness (at least 3mm), remaining maintenance mileage (over 6,000 km), and sufficient brake disc and pad thickness, every item is meticulously inspected and restored. Vehicles that have been flooded, passed through trains, or have significant structural damage or deformation are excluded. Every BMW Certified Pre-Owned vehicle comes with BMW 24-hour roadside assistance, trade-in service, test drive, a minimum 12-month or unlimited mileage warranty, BMW Financial Services professional loan services, and assistance with vehicle transfer.
