Not all Buick vehicles are eligible to be sold as a certified pre-owned (CPO) car or SUV. Buick’s CPO vehicles are all five years old or younger. They can have no more than 75,000 miles on them and must pass a Vehicle History Report.

Additionally, all vehicles considered for the program must pass a 172-point inspection and reconditioning process to be eligible. If the car or SUV fails at any point during the testing, it cannot be sold as a certified pre-owned Buick.

Inspection Process

The 172-point CPO inspection and reconditioning process covers everything from the engine to the daytime running lights to the seats and the lumbar support. During inspection, all vehicles must also have any outstanding recalls addressed.

If any part of a prospective CPO Buick vehicle fails inspection, the dealership has to repair it. If the failure isn't repairable, the vehicle cannot be sold as CPO.


Each CPO Buick comes with two warranties. The first is a six-year/100,000-mile powertrain warranty. A 12-month/12,000-mile bumper-to-bumper warranty also comes with each CPO Buick purchase. Both warranties come with a $0 deductible.

Each CPO Buick also comes with two complementary routine maintenance visits. Some dealerships increase this incentive as part of a promotion.

If you are dissatisfied with your purchase, return your CPO Buick to the dealership within three days or 150-miles of purchase and you can exchange it for another Buick, Chevrolet, or GMC.


When you buy a CPO Buick, you may be eligible to receive a free three-month trial of the OnStar Guidance Plan and three years of the OnStar Basic Plan. To qualify, buyers must be new OnStar subscribers.

CPO Buicks that can receive SiriusXM programming come with a complementary three-month subscription to the service.

Also, CPO Buicks come with a Carfax vehicle history report, which tells you if the vehicle you are looking to buy has been in an accident or had title issues, and provides a simplified maintenance record.

How Does It Compare to Rivals?

Not all CPO programs are created equal, though the Buick CPO program is comparable to others offered by mass market and luxury manufacturers. Buick inspects more items for their CPO program than Toyota does, though Honda and Lincoln inspect more components than both companies. Most companies offer a similar warranty.

How to Buy a Buick CPO Vehicle

There are many advantages to buying a CPO car over a traditional used car from a dealer lot. However, the price of CPO cars may be higher than the price of traditional used cars.

Many car companies offer special financing deals for CPO vehicles throughout the year, especially as new model years arrive. Each month we update our best used car deals to include the latest offers.
