Documentation
Introduction
This endpoint returns four mileage adjusted valuations. By using the optional vehicle_condition parameter (0-100 - where 0 is very poor and 100 is retail-ready), the valuations will also be condition adjusted. Additional metrics providing insight into market supply & demand, market condition are also returned. Days to Sell and Location Market Rating are based on postcode and advertised price.
