Years, battery and range are catalogue data (WLTP, range converted to miles; varies by variant and equipment). Battery is net capacity where known. Prices, counts, mileage and price ratings are AutoUncle market data from October 2026. Good or Super price means the listing price is below AutoUncle's valuation of the car. Shares and time on site are calculated for cars with a valuation; time on site so far is how long the current listings have been up (median).
