Autotrender records every Triumph GT6 listing on Autotrader UK twice a day and groups them by registration year. 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 figures are only stated once at least 5 sales have been recorded.
