Valuations explained

A Cazana valuation turns a vehicle and its mileage into a market valuation. Knowing how the figures are produced explains behaviour that can otherwise look surprising.

How valuations are produced

Valuations are derived from live market data, the prices vehicles are actually advertised and sold at, combined through Cazana's machine learning models. The models account for the specifics of the vehicle, not just its make and model.

What this means in practice

• Valuations are not fixed for a calendar month. The market moves, and so do the figures. Do not assume a value will be identical if you request it again later.
• Small differences between vehicles produce different valuations. Mileage and date of first registration are the largest levers, alongside a range of other inputs. Two vehicles that look alike can value differently, and that is expected.
• Pass the most accurate mileage you have. Mileage is one of the biggest levers, so if you omit it the value falls back to an estimate.

If two near-identical vehicles return different figures, this is usually why: the model is responding to differences that are not obvious at a glance.
