Smarter spec matching Paste a listing's description straight into your scan — SpecScan reads the options and equipment and factors them into the valuation, so the number reflects the actual car, not just the VIN. Color matters now When a vehicle wears a rare or limited color, we say so in plain language — and show exactly how much of the value comes from it. Straight talk on thin markets When there aren't enough comparable listings to establish a true market value, we tell you that directly instead of dressing up a guess. Plus reliability improvements and bug fixes.
