The average price of a used car recorded an annual increase of 4% in November, which marks the lowest increase since August 2017.
Year-on-year (YoY) growth reached a peak of 7% in June this year but has been slowing each subsequent month.
It reflects a similar trend seen across the fuel types, with diesel reaching a peak (6%) in July 2018 but gradually slowing to 4% in November.
Petrol’s rate of growth decelerated even more significantly, from 11% in December 2017, to just 4% last month. AFVs have also been gradually slowing since December, from 9% to 4%.
Those are the key findings from the Auto Trader Retail Price Index, which combines and analyses data from 500,000 trade used car listings every day.
The record high was mirrored across the various fuel types tracked by the Index. The average price of a used petrol vehicle last month was £11,202, the highest rate recorded, as was both the £20,828 average price for alternatively fuelled vehicles[2] (AFVs) and the £19,978 for pure electric vehicles (EV). The average sticker price for a used diesel was £14,630, which was just £73 less than October’s record high of £14,556.
