Built-In Value

The Certified Standard
Hand-selected for you

These aren't just used vehicles. These are Certified Pre-Owned vehicles, and it takes a lot to earn that Certified status. Here's what it takes to become a Certified Pre-Owned vehicle:

  • Must be Chevrolet, Buick or GMC vehicle
  • Must be less than six model years old
  • Must have fewer than 75,000 vehicle miles
  • Must have a clean title
  • Must pass our 172-Point Vehicle Inspection and Reconditioning Process

Two Auto Warranties

When we say "no worries," we really mean it. Buy a Certified Pre-Owned vehicle from Chevy, Buick, or GMC and you're protected from the moment you leave the lot. Why? Because all of our vehicles come with two factory-backed auto warranties that combine to provide fantastic coverage: a longer 6-Year/100,000-Mile1 Powertrain Limited Warranty and an impressive 12-Month/12,000-Mile2 Bumper-to-Bumper Limited Warranty, both with $0 deductible.

Bumper-to-Bumper Limited Warranty

You can feel confident in your decision to buy a Certified Pre-Owned Vehicle from Chevy, Buick or GMC. Each vehicle comes with the security of our Certified Pre-Owned 12-Month/12,000-Mile2 Bumper-to-Bumper Limited Warranty in addition to any remaining original factory Bumper-to-Bumper warranty, all with a $0 deductible.

What's Included

Almost every part of our vehicles is covered under the 12-Month/12,000-Mile2 Bumper-to-Bumper Limited Warranty (excludes normal wear and maintenance items). See below for the list of exclusions.

What's Not Included

  • Tire damage or wear
  • Damage due to bedliners
  • Damage due to accident, misuse or alteration
  • Collision, fire, theft, freezing, vandalism, riot, explosion or objects striking the vehicle
  • Misuse of the vehicle such as driving over curbs, overloading, racing or other competition. (Proper vehicle use is discussed in the owner manual.)
  • Alteration or modification to the vehicle, including the body, chassis or components, after final assembly by Chevy, Buick or GMC.
  • Coverages do not apply if the odometer has been disconnected, its reading has been altered, or mileage cannot be determined.
  • Damage or corrosion due to environment, chemical treatments, and/or aftermarket products
  • Damage due to insufficient or improper maintenance
  • Damage due to contaminated or poor-quality fuel

Improved 6-Year/100,000-Mile Powertrain Limited Warranty

Every Certified Pre-Owned vehicle from Chevy, Buick, and GMC comes with a 6-Year/100,000-Mile1 Powertrain Limited Warranty, including Roadside Assistance and Courtesy Transportation3. We believe in our vehicles and aren't afraid to stand behind them.

Scheduled Maintenance

Maintenance to Keep You Going Strong
Exclusive CPO Scheduled Maintenance

Having your vehicle in tip-top shape gives you the confidence to move forward. That's why we provide you with two scheduled maintenance visits1 within 2 years/24,000 miles. More confidence means more adventures ahead. Services performed include:

  • Oil and oil filter changes
  • Tire rotations
  • Multi-point inspections

For us, it's all about providing you with value, certainty and satisfaction for every mile and milestone ahead.

The coverage begins when you purchase your Certified Pre-Owned vehicle from a participating Chevy, Buick, or GMC dealer. This exclusive program includes two maintenance visits and lasts for 2 years or 24,000 miles, whichever comes first. Scheduled Vehicle Maintenance is also transferable to subsequent owners if the vehicle is still within the terms of 2 years or 24,000 miles. If you already own a Certified Pre-Owned Chevy, Buick, or GMC that has our exclusive 2-Year/24,000-Mile CPO Scheduled Maintenance Program,1 find your nearest dealer for service.

  1. Maintenance visits must occur within 2 years or 24,000 miles of vehicle delivery, whichever comes first. Does not include air filters. See participating dealer for other restrictions and complete details.

Vehicle Inspection

Inspected to Meet Your High Standards
Vehicle Inspection

We check everything on our Certified Pre-Owned vehicles - from the brakes to wipers to the A/C to keep you cool.

Our detailed 172-point vehicle inspection is one of the most comprehensive in the industry. Before any Chevrolet, Buick, or GMC used vehicle earns the Certified Pre-Owned title, it must first meet all of our requirements.

So we check just about everything - from the A/C to the shocks, right down to the floor mats and the undercarriage. It's the Certified difference.

Important Recall Information: Before a Certified Pre-Owned vehicle is listed or sold, GM requires dealers to complete all safety recalls. However, because even the best processes can break down, we encourage you to check the recall status of any vehicle at

Vehicle Exchange Program

We're not satisfied until you're satisfied.
Vehicle Exchange Program

Finding the perfect fit is key. So, if for some reason something changes, you have 3 days/150 miles to exchange1 your Certified Pre-Owned vehicle for something that you'll love. Did your lifestyle unexpectedly change? Are you adding a new member to the family? Not loving the color? Whatever it is, our exchange policy allows you the option to find a better fit for your needs. It's just another one of the perks we offer that make Certified Pre-Owned vehicles miles above used.

1 Whichever comes first. Vehicle exchange only. Limitations apply. See dealer for details. See the Vehicle Exchange Policy
