'Certified' Doesn't Always Mean Manufacturer CPO
To further complicate matters, not all cars labeled "certified" are manufacturer-certified pre-owned cars. Here are a few of the ways you might encounter a certified car that is not part of a manufacturer CPO program.
Dealer Certified: Dealers will sometimes call their used vehicles "certified" because they've put them through a basic inspection and reconditioning and given them a third-party warranty. Dealers also sometimes take a vehicle from another make, give it a third-party warranty and label it as a "certified" car. (Think of a Chevrolet dealer selling a "certified" Ford.) This kind of thing can create a lot of confusion for consumers.
Third-party extended warranties might not cover the same items as the manufacturer's CPO warranty. The third-party warranties might require that you get the car serviced only at that dealership. Additionally, you might get fewer or none of the additional perks that you'd get from a manufacturer CPO program.
The cardinal rule is this: Only a manufacturer's franchised dealer can sell that manufacturer's CPO vehicles. This means that if a dealership can sell new BMWs, then it can also sell BMW CPO vehicles. It cannot, however, offer vehicles from other brands as CPO cars.
If a car dealer tells you he will "certify the car" for you after you buy it, don't agree to it. No car can be certified after the fact. It probably means that the dealer wants to sell you an extended warranty under the guise of manufacturer certification.
Carfax Certified: Cars with this label are not CPO vehicles. They have not met the manufacturer's criteria for inspection. They also don't come with the manufacturer's factory extended warranty. The Carfax certification refers to the guarantee that its accident data is correct and the clean-title vehicle in question was indeed never in an accident.
NIADA Certified Pre-Owned: You might also encounter used cars labeled "NIADA Certified." Dealerships offering these cars are members of the National Independent Auto Dealers Association (NIADA). NIADA has created its own certification program that offers benefits that are similar to manufacturer CPO programs. There's a multipoint inspection, limited warranty and roadside assistance. There are options to increase the coverage and lower the deductible for a fee.
One major difference is that this certification can be applied to vehicles that wouldn't typically qualify for a manufacturer CPO program. The NIADA certified program can cover a vehicle that's up to 14 years old, while manufacturer programs would not cover a vehicle that's more than 6 years old.
NIADA and the dealerships selling the vehicle aren't the administrators of the limited warranty. That's handled by Warrantech Automotive Inc. As with any third-party extended warranty, it's a good idea to research the company and read consumer reviews before you buy product.
