Figures from Auto Trader showed that 4,822 second-hand Teslas were advertised on the car site in February and 4,639 in January, a significant increase on previous months.

Tesla shares have fallen by more than 30pc this year as it faces falling sales in multiple markets. This week, figures have shown orders falling by 76pc in Germany, 72pc in Australia and 49pc in China.
