How this is worked out

These are asking prices from adverts, not what cars sold for. A model is listed when the median asking price of all its used cars for sale is under $20,000 and it has at least 10 cars for sale, so some of its cars will cost more. Cars with very low kilometres (usually ex-demo) are left out. Where a model has enough cars at 1 to 2 and at 4 to 6 years old, we also show how much of its price it keeps.

Worked out from cars for sale on 15 November 2026. Car counts are rounded and shown as “about”.
