When Is the Best Time to Buy a Used Car in the UK?(2026 Guide)

Timing matters more than most people realise when buying a used car. The same car can cost noticeably more or less depending on when you make your move. If you have the flexibility to wait for the right moment, a little patience can save you hundreds of pounds. Here is when the used car market tends to work in the buyer's favour, and how to make sure you buy well whenever you buy.

Just after the plate change (March and September)

Twice a year, in March and September, the registration plate changes and a wave of new cars hits the road. That matters to used buyers because almost every new car means a part-exchange coming the other way. Dealers suddenly have more used stock than they want, and they are keen to keep it moving. With the September 76 plate now out, forecourts are filling with nearly-new part-exchanges and ex-demo cars, so it is one of the better windows of the year for both choice and price.

The end of the month, quarter and year

Dealers work to targets, and those targets fall due at the end of the month, and more heavily at the end of a quarter (March, June, September and December). A salesperson who is one car short of a bonus has every reason to be flexible on price. The quietest stretch of all is the run-up to Christmas, when footfall drops and dealers are often willing to do a deal to shift stock before the year closes.

When a model is updated or replaced

When a manufacturer facelifts or replaces a model, the outgoing version instantly looks like yesterday's car, even though it drives exactly as well as it did the week before. Prices on the superseded model tend to soften, which can make it a smart buy if you are happy to forgo the very latest badge.

Timing is only half the story

Buying at the right moment gets you a better price, but it does not tell you whether the car itself is sound. Whenever you buy, and especially when the market is busy and cars are moving quickly, do your homework before you commit.

Start with a full history check, with data provided by Experian, on any car you are serious about. A full history check reveals what a test drive and a friendly chat cannot: whether there is outstanding finance still owed on the car, whether it has ever been recorded as an insurance write-off, whether it is flagged as stolen, scrapped or salvaged, whether it has been imported or exported, whether the plates or colour have been changed, and how many previous keepers it has had. If something flags up that the seller did not mention, you have every reason to renegotiate or walk away. If it comes back clean, you can buy with genuine peace of mind.

Know your budget before you fall in love

Decide your ceiling before you start looking, and if you are buying on finance, work out an affordable monthly figure first. That keeps you calm at the point of sale and stops you being talked upward. MotifyMe can introduce you to car finance through an FCA-authorised credit broker, and an initial check is usually a soft search that does not affect your credit score, so you can understand your options before you commit. Explore your finance options when you are ready.

When you have found a car that is checked, sound and within budget, you have bought well, whatever the date on the calendar. Browse finance-ready used cars on the MotifyMe marketplace to start your search.
