Frequently Asked Questions

How accurate is the Deal Score?
The Deal Score combines 6 weighted factors: price position vs market, mileage adjustment, depreciation curve, price history trends, dealer quality, and market supply. Each factor is calculated from real listing data in our database, not estimates. The score is most reliable for popular models with 50+ comparable listings.
Where does the market data come from?
Our data comes from active listings on AutoTrader — currently 27,000+ vehicles across 100+ models. We aggregate real asking prices, mileage, trim levels, and dealer information to build a comprehensive market picture. Data is refreshed daily through automated scraping.
How is the fair market value calculated?
We calculate fair market value using the median price of comparable vehicles, adjusted for mileage, year, trim, and regional variations. The fair range (middle 50%) gives you a realistic price band to work with when negotiating.
Is my privacy protected?
Yes. Listing URLs are analyzed anonymously. We do not store personal information, track individual users, or share data with third parties. The listing URL is used only to fetch the vehicle details and perform the analysis.
Is SmartCarAgent free?
