Fastest-selling used cars revealed by Auto Trader

Auto Trader has revealed the fastest-selling used cars in the UK in December, with the all-electric Kia Niro topping the list.

It retained its position at the top of the charts for the second consecutive month, selling in just 15 days on average. This compares to the market average for the month of 34 days.

Five more electric models also made the list of the 10 fastest-selling used cars, including the Nissan Leaf and the Tesla Model Y, which came in second and third respectively.

Meanwhile, electric was the fastest-selling fuel type for the third month in a row, finding buyers in an average of 27 days so far this month. This is four days faster than December 2024.

Electric vehicles

Marc Palmer, Auto Trader head of strategy and insights, said: “EVs have ended the year firmly in the fast lane. It’s clear in the data that electric vehicles, particularly ‘middle-aged’ models, are hitting a sweet spot, giving drivers affordable and clean motoring as well as retailers a path to profit.

“Looking ahead to 2026, the winners will be those who stay closest to the data and leverage the latest market intelligence. With supply of 5–7-year-old cars set to tighten next year, retailers who adapt and diversify their forecourts will be well positioned to make the most of a changing market.”
