Buying a pre-owned vehicle comes with questions—some which may not get answered until it’s in your driveway. If you have been researching your options in Ontario, California, you may have come across the term “CPO,” or “Certified Pre-Owned.”  This is far more than a simple label. The INFINITI CPO program is designed to give buyers confidence, transparency, and real value when choosing a pre-owned luxury vehicle, rather than just a handshake. 

2022 GX80 - What is CPO and Why Does It Matter? Understanding the INFINITI Certified Pre-Owned Program 

What Does Certified Pre-Owned Actually Mean? 

CPO stands for Certified Pre-Owned, and it refers to a used vehicle that’s gone through a rigorous manufacturer-backed evaluation process before being offered for sale. Many brands offer a CPO program, all with different, but similar requirements—and not every used car qualifies. True to its luxury status, INFINITI CPO vehicles are held to a very high standard. The INFINITI must be less than 5 years old and have fewer than 60,000 miles just to be considered for the program. Once a vehicle passes that initial screening, it moves on to a thorough 167-point inspection process conducted by trained INFINITI technicians. 

The INFINITI Inspection Process

The inspection is one of the most important parts of what makes a CPO vehicle different. INFINITI uses a comprehensive 167-point inspection to evaluate the mechanical, electrical, and cosmetic condition of each vehicle. Certified technicians examine everything from the engine and transmission to the brakes, tires, and interior components. Any parts that do not meet INFINITI’s standards are repaired or replaced before the vehicle is certified. This process removes much of the guesswork that typically comes with buying used.   

Certified Pre-Owned vs. a Standard Used Car  

This is another frequent CPO FAQ that buyers bring up—what actually separates a CPO vehicle from a regular used car? The short answer is accountability. A standard used vehicle has no manufacturer backing, no guaranteed inspection process, and no standardized warranty. An INFINITI CPO vehicle comes with a CARFAX® BuyBack Guarantee, documented history, a completed inspection report, and manufacturer-supported coverage. That combination of transparency and protection is what sets certified vehicles apart. 

Warranty Coverage You Can Count On

One of the biggest advantages of purchasing a CPO vehicle is the warranty. INFINITI CPO vehicles are available in a range of tiers that vary by age and mileage, but always come with warranties. The standard INFINITI Certified Pre-Owned warranty extends for 6 years or 75,000 miles. It also includes INFINITI Roadside Assistance for 84 months or 100,00 miles, as well as towing assistance, car rental reimbursement, and trip interruption coverage if you’re far from home. These protections can provide real peace of mind, especially compared to purchasing a vehicle with no warranty at all.

If you want the value of a pre-owned vehicle without sacrificing the assurance of manufacturer backing, a CPO INFINITI could be an excellent fit. The combination of a thorough inspection process, tiered warranty options, and ownership benefits makes CPO a compelling choice for informed buyers.
