AutoUncle has valued used cars independently since 2010. We were the first to put a price rating on every listed car, and we proved that a car's market value can be set by independent algorithms instead of by hand, something the industry long held could not be done. Dealers, marketplaces and other professionals across Europe have relied on those valuations for years. Data Services distils that experience into one API.
No seller pays for a price. Every valuation comes from what the market shows, read by our own algorithms, never from opinions or negotiations.
