Powered by the superior vehicle history data network from CARFAX Canada, and up-to-date market information, the History-Based Value output is quite complex and requires many pieces of information to calculate. If you suspect that our valuation output is incorrect, the first step will be to confirm that all entries about your vehicle are accurate. i.e., odometer reading, trim package, engine size, etc. Once you’ve confirmed this and your valuation still doesn’t look quite right, we’d love to hear about it. Please contact us to provide feedback.
