Looking to score a good used car deal but not sure if the timing’s right? Read on to find out when is the best time to buy a used car in the UK.
Buying a car is expensive business, with used car prices fluctuating throughout the year. So, knowing when is the best time to buy a used could help you snag a great deal. This guide will walk you through how careful timing could help you find the best possible price.
When is the best time to buy a used car?
Generally speaking, the best time to buy a used car is at the end of the month, especially at the end of a quarter: March, June, September, and December. Dealers will be keen to meet their sales targets and, in turn, may offer better deals.
Shopping during the winter months, or right after the release of the new model of the used car you’re looking at, may also mean price reductions.

How new number plate releases affect used car prices
New number plates come out twice a year, in March and September, and they tend to shake up used car prices. In the months before the new plates drop, lots of people trade in their old cars for shiny new ones, which means there’s suddenly a lot more used cars on the market. With all that extra stock, dealers often lower prices a bit to make space and shift older models. Cars with the “old” plate can also lose value more quickly, just because they feel less current.
That’s why the best time to buy a used car is before these plate changes: so February and August are your sweet spots. There’s usually more choice, better deals, and more room to haggle.
How new model launches affect used car prices
When a new car model launches, especially with major upgrades, it usually drives down the price of the older version. Demand drops, supply rises (as owners trade in), and prices soften, especially for popular car types such as SUVs.
These price drops are more noticeable after a full redesign, not just a minor update. That’s why the best time to buy a used car is right after the new model hits the market – you’ll see even more options, better deals, and more room to negotiate. Pair that with the end-of-year months (October to December), when sellers are eager to clear out stock, and you’re in a strong position to save.
How seasonal trends affect used car prices
Used car prices rise in spring and early summer when demand spikes: graduations, family holidays, and warm-weather buyers are some examples of what drives this. In fall and winter, demand drops as budgets tighten with Christmas around the corner and fewer people are shopping, making sellers more flexible.
With this in mind, the best time to buy is late fall to early winter (October to December). The market slows, dealerships want to hit year-end goals, and you’ll likely find better deals and more room to negotiate.
How holiday periods affect used car prices
Holiday periods can impact used car prices thanks to more sales events and shifting buyer behaviour. Major holidays, especially year-end ones such as Black Friday and Christmas, often bring greater promotions that make prices more competitive.
End-of-year holidays are your best bet as dealers are motivated to hit sales quotas and clear inventory, and with fewer buyers around, you’ll face less competition.
Buying a used car for the new year can also be a good idea as not many people are focused on buying new cars during the Christmas period, so you can get the best new year car deals in December, followed by New Year’s January car sales.
