Benefits of Certified

You also get a minimum of 3 months or 5,000 kilometres (whichever comes first) Used Vehicle Limited Warranty when you purchase a Certified Pre-Owned Vehicle. That's standard. If your budget permits, you can extend or upgrade to an even more comprehensive Certified Pre-Owned Vehicle Protection Plan. CERTIFIED MANUFACTURER'S WARRANTY
You might not worry much about the condition of your hose clamps or the vacuum system or the brake pads. You'll never have to, either, with one of our GM Certified Pre-Owned Vehicles. Before they reach the sales floor, each one of our vehicles is meticulously looked over by a licensed mechanic. That means by the time you look at them, every single vehicle has passed our painstaking 150+ point inspection. CERTIFIED 150+ POINT INSPECTION
It's going to be a great ride, especially knowing you're covered with a minimum of 3 months or 5,000 kilometres (whichever comes first) of 24-hour roadside assistance. CERTIFIED ROADSIDE ASSISTANCE
You should be completely satisfied with your Certified Pre-Owned Vehicle. If for any reason you're not, you can exchange it within the first 30 days or 2,500 kilometres, whichever comes first. CERTIFIED EXCHANGE PRIVILEGE
If you’re considering a pre-owned vehicle or your current vehicle’s connected services are inactive, you can still enjoy many or all of the same features and services found in new vehicles. ONSTAR
