What is the CPO Advantage?

Each pre-owned vehicle on our lot (selling over $10,000) comes equipped with a full Certified Pre-Owned benefits package. The 172-point inspection ensures that only the most worthy vehicles are being sold at Roy Foss Cadillac Thornhill. The included warranty, roadside assistance and exchange policy guarantees peace-of-mind for customers and their families. GM calculates that this program adds up to $2,135 worth of value for the vehicle (when compared to a non-Certified unit). Knowing we’re selling safe, quality vehicles makes the process worth every penny. Feel free to read more on each of our CPO perks or give us a call to speak directly with a Pre-Owned expert.



If, for any reason, you’re not completely satisfied with your Certified Pre-Owned vehicle you may exchange it within the first 30 days or 2,500 kilometres (whichever comes first) of the date of purchase for any other eligible Certified Pre-Owned Vehicle. If the purchase price of the replacement vehicle is less than the purchase price of the vehicle being returned, you’ll receive credit for the difference. If the purchase price of the replacement vehicle is more, you simply pay the difference.

Because our vehicles are only serviced with factory-approved parts, we gladly back every Certified Pre-Owned vehicle with a manufacturer’s warranty. We also include a Used Vehicle Limited Warranty for the first three months or 5,000 kilometres (whichever comes first). There’s also an opportunity to extend or upgrade to an even more comprehensive Certified Pre-Owned Vehicle Protection Plan. You can rest easy—existing warranties are transferrable should you ever choose to sell.
