Beyond the assurance of an exhaustive certification process and 24-hour Roadside Assistance, every Certified Pre-Owned Mercedes-Benz now comes with industry-leading coverage: an unlimited-mileage warranty for one year that can be extended for up to two additional years. So no matter what your odometer reads, your confidence will know no bounds [1].

Certification
To qualify for Pre-Owned Certification, a Mercedes-Benz vehicle must meet stringent criteria and pass a rigorous 150-point inspection. This includes a detailed inspection of vehicle structure, a complete examination of all interior materials, features and functions, a check of all fluids, filters and engine functionality and more.
Warranty
Every Certified Pre-Owned Mercedes-Benz is covered by any remaining portion of the Mercedes-Benz four-year/50,000 mile New Vehicle Limited Warranty. Then, the CPO Limited Warranty provides comprehensive coverage for another 12 months with unlimited miles. This means up to 5 years of unlimited mileage coverage, extending to the engine and powertrain, steering, suspension, brakes (excluding wear of discs and pads), electrical system, climate control system, and more [1].

Additional Benefits
24/7 Personal Assistance
You're just a phone call away from 24-hour Roadside Assistance, Trip Interruption, trip routing, technical help or Sign & Drive Service, which offers jump starts, tire changes and refueling.
Nationwide Dealer Support
Your Certified Pre-Owned Mercedes-Benz is supported by over 300 authorized dealers nationwide, all of whom honor the standard Certified Pre-Owned Limited Warranty and Extended Limited Warranty.
Vehicle Exchange Privilege
Every Certified Pre-Owned vehicle is sold with a seven-day/500-mile Exchange Privilege. If you're not satisfied in that time, your dealer will exchange it for another CPO vehicle of equal or greater value if you wish to pay the difference [1][2].
