Relied on where a valuation must hold up
Over the years, banks, insurers, leasing companies, dealers and marketplaces have used AutoUncle to value cars, and so has the Danish Tax Agency (SKAT).
Value every car in the fleet from its VIN, follow its market value over time, and decide when to defleet with the comparable cars on the market. One API for leasing, rental, subscription and company fleets across 14 European markets.
Decode VINs, look up Danish plates and German HSN/TSN codes, and attach catalogue IDs and specifications to every car.
Revalue the fleet in batch, in each market's currency, and compare market values with book values.
Time sales with market values, price ratings and how long comparable cars stay on the market.
Price each car for the channel you sell it in, at dealer or private-sale level, and check your asking prices against the market.
Each valuation is for one market, in that market's currency and mileage unit. Send the mileage in whatever unit your system uses, restrict API keys to the markets each team works in, and read every result back by ID.

Remarketing decisions are reviewed later. Every valuation keeps the identified car, its ranges and the comparable cars behind the price, readable by ID for 13 months.
Make, model, generation and drivetrain, with the source of every value: your input, the register, the listing text, a photo or an assumption.
80%, 95% and 99% price ranges, a precision grade with a sentence explaining it, and how much comparable market data stands behind the estimate.
Up to five similar cars on sale and five that recently left the market, as anonymized examples: year, rounded mileage, rounded asking price, price rating and days on market. Never the seller, a link, dates, the plate, the VIN or photos. One extra credit, only when listings are returned; not available in Denmark.
Disclaimers and data-source attributions on every result. Live results are kept for 13 months and can be read back by their ID.

A VIN usually settles the brand, model and year. Add the mileage, and the drivetrain if your register has it, for a precise valuation. The result tells you which detail would help most.
