What a Giant Defy 1 sells for, by model year

Median asking price for each model year, measured from 17 real UK Giant Defy 1 listings that state a model year. These are last-advertised asking prices, not confirmed sale prices. The other 29 listings behind the typical price above don't state a model year, so they can't be placed on this table. Compare a year below against £300, the median across every listing that does state one, rather than against the £300 figure above, which pools both.

Source: Cyclesite UK listings data, refreshed continuously. Median of asking prices per model year. The second figure is a 95% confidence range for that year’s typical price: with this many listings we can say the middle of the market sits somewhere in that span, not exactly where. Years with fewer than six listings are omitted, because below six no range can honestly be quoted at all. Where two years’ ranges overlap heavily, treat the gap between them as unproven rather than as depreciation.
