Autotrender records every BYD listing on Autotrader UK twice a day (since 26 May 2026). A car counts as sold when its advert is removed, and its sold price is the final asking price before it came off; days to sell run from the advert's listing date to its removal. Medians are used throughout, and months with fewer than 5 sales are not used to call a trend.
