The Kia Niro (three to five years old), an all-electric model, was ranked as the fastest selling used car in the UK for December, according to Autotrader.  

The model took an average of 15 days to sell, making it the fastest selling used car for the second consecutive month.  

Used cars overall were sold on average within 34 days in December, a figure that matches last year’s seasonal trend, according to Autotrader data.  

Electric vehicles (EVs) continued to lead as the quickest selling fuel type for the third month in a row.  

So far this December, EVs have taken an average of 27 days to sell, which is four days faster than during the same period last year. 

The Niro appears alongside five additional EVs on this month’s fastest-selling list. The Nissan Leaf (electric, three to five years old) and the Tesla Model Y (electric, three to five years old) take the second and third positions, respectively. 

‘Middle aged’ cars those between three and five years old comprise 80% of December’s top ten rankings. 

For used EVs specifically, those aged three to five years sold even faster at 22 days on average during December.  

This is nearly two weeks quicker than the overall average for all used cars sold during the month, according to Autotrader’s findings. 

Of the ten quickest selling used cars listed in December, eight are alternatively fuelled vehicles (AFV).  

Autotrader Strategy and Insights head Marc Palmer 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.”
