Mercedes-Benz GLB Class Emerges as Fastest-Selling Used Car of 2024

The Mercedes-Benz GLB Class has been crowned as the fastest-selling used car of 2024, according to UK-based automotive platform Auto Trader. With a median selling time of just 16 days, the GLB Class outperformed other models, including the A Class, which took 16.5 days to sell. These figures are significantly lower than the average selling time of 30 days for used cars in 2024.

The trend of faster-selling used cars continued into 2025, with vehicles currently selling in about 39 days, marking the quickest start to a year since Auto Trader began keeping records in 2019. Electric vehicles (EVs) emerged as the top-selling fuel type, with a median selling time of 29 days, faster than petrol and diesel vehicles.

The demand for used EVs has been on the rise, with EVs selling four days faster in the latter half of 2024. In January 2025, used EVs sold in just 35 days, a day faster than in January 2024 and almost two weeks quicker than in January 2023.

Interestingly, three to five-year-old electric models sold even faster, taking just 23 days to sell compared to 29 days for petrol cars of the same age. This trend has continued into 2025, with middle-aged electric cars selling over a week faster than the average used car.

However, nearly new EVs, up to a year old, are among the slowest-selling used cars, taking nearly 42 days to sell. This can be attributed to the higher price point of nearly new electric cars, which cost almost double that of three to five-year-old models.

Despite the challenges faced by the automotive industry, car buyers have shown a willingness to invest in premium used cars, with SUVs dominating the list of top-selling models in 2024. Auto Trader’s data and insight director, Richard Walker, highlighted the exceptional market performance in 2024, with rapid sales, robust demand, and stable prices.

Walker also emphasized the growing popularity of used EVs, especially middle-aged models that have become more accessible to buyers. As prices become more competitive, car buyers are increasingly willing to make the switch to electric vehicles.

Overall, the data from Auto Trader paints a positive picture for the used car market, with electric vehicles leading the way in terms of sales and demand. As the automotive industry continues to evolve, it will be interesting to see how these trends shape the market in the coming years.
