The UK used car market could be heading for its strongest year since 2017.
Auto Trader expects around 7.95 million used cars to change hands during 2026, up 1.9% on last year. With forecast new car registrations, the total UK car market could reach 10.17 million transactions, making 2026 its busiest year since 2019.
For UK car dealers, the headline is encouraging. Buyers are still active, cars are moving quickly, and the market has continued to grow despite pressure on household budgets.
There is also a more useful question for dealers: where is that demand going, and how do you turn it into profitable sales?
The year started steadily rather than spectacularly.
SMMT recorded 2,016,232 used car transactions in Q1 2026, down just 0.2% on the same period in 2025. The market then returned to growth in Q2, with 2,009,318 vehicles changing hands. That took the first-half total to more than 4.02 million transactions, up 0.2% year on year.
Activity picked up further during the summer.
Auto Trader reported that used car transactions rose 2.6% year on year in August, with franchise dealers, independents and car supermarkets all recording growth for the first time in 2026.
That momentum helps explain why the full-year forecast has moved higher.
A market approaching eight million used transactions creates plenty of opportunity. Where those opportunities sit will vary by stock age, fuel type, price and local demand.
Several things are supporting used car sales.
Consumer confidence has gradually improved. The GfK Consumer Confidence Index reached -13 in September 2026, its third monthly rise in a row and six points higher than a year earlier. People were also more positive about their personal finances than they were 12 months ago.
Buyers remain careful with larger purchases, though. GfK's Major Purchase Index stood at -8 in September.
That matters on a forecourt.
Many customers still want or need to change their car, but price, monthly cost and overall affordability continue to shape what they buy.
Used vehicles can fit that need well, particularly where buyers can choose from different ages, specifications and finance options.
Auto Trader's own consumer research also found that seven in 10 people using its platform plan to buy a vehicle within the next six months.
Demand is there. Dealers still need to make the right stock and pricing decisions to capture it.
Stock turn gives another useful view of market health.
In September, used cars were taking an average of 29 days to sell, according to Auto Trader. That was one day quicker than August and in line with the same point last year.
That follows the pattern we looked at in our guide to why used cars are selling in around 29 days.
A healthy average does not make every car a fast seller. There are wide gaps between individual models.
September's fastest-selling list included practical hatchbacks and compact SUVs such as the Toyota Yaris, Kia Sportage and Hyundai Bayon. Some examples were leaving forecourts in fewer than 20 days. At the other end of the market, certain models were taking 40 days or more.
That makes vehicle-level data more useful than a national average when dealers are deciding what to buy.
Look at what customers are searching for, what generates enquiries locally, how quickly previous examples have sold and the margin left after preparation.
Volume alone does not pay the bills. Buying the right stock does a much better job of that.
The used car market remains uneven.
In August, Auto Trader recorded an average used car asking price of £17,131. Like-for-like prices were broadly stable year on year, while transactions continued to grow.
The picture changes once you look below the overall average.
Vehicle age, fuel type and model can produce very different results. We recently looked at this in our guide to used car prices and what dealers should do next.
That difference matters when the market gets busier.
Dealers may see more enquiries overall, but tying cash up in the wrong vehicles can still slow stock turn and squeeze margin.
Regular stock reviews should cover days in stock, enquiries, competing adverts, current trade values and actual retail demand. A vehicle that has generated several strong enquiries in its first week needs a different approach from one approaching day 60.
The market average gives you context. Your own stock data tells you what to do next.
Affordability continues to influence the type of cars customers consider.
Auto Trader reported earlier this year that 10-to-15-year-old used cars were seeing some of the strongest price growth in the market, as buyers continued to search for vehicles at more accessible price points. Its July analysis showed prices in that age group running 7% higher year on year.
There is a practical point here for dealers.
Older stock can give customers more choice within a fixed budget, but condition, preparation costs, warranty expectations and suitable finance terms all need closer attention.
Buying purely because a vehicle looks cheap at trade can quickly become expensive after preparation.
Dealers serving near-prime customers should pay particular attention to this part of the market. We have looked at the changing economics of older stock in more detail in our guide to older used cars and near-prime finance.
More market activity means more opportunities walking through the door, calling the dealership or submitting an online enquiry.
Those customers will not all fit the same lender profile.
Some will have clean credit files. Others may have missed payments in the past, changed jobs, moved home or experienced a period where their finances became harder to manage.
A broader finance panel can help dealers deal with that mix.
Marsh Finance works with UK dealerships to support customers across the near-prime market, using rate-for-risk pricing and a mix of automated and manual underwriting.
That becomes particularly relevant when customers are focused on the monthly figure.
“Customers are still buying cars, but affordability remains a major part of the conversation,” says Sean Ryan, Head of Sales at Marsh Finance. “Dealers that understand their customer early and have access to lenders covering different credit profiles give themselves more routes to get a suitable deal agreed.”
The aim should be a finance conversation that helps the customer understand what they can reasonably afford and gives the dealership a clear route through the application.

A forecast of 7.95 million transactions gives dealers a healthy market to work with through the rest of 2026.
The practical response starts with stock.
Use live demand data when buying. Watch days to sell at model level rather than relying only on broad market averages. Keep reviewing advertised prices as local competition changes.
Then look at conversion.
Respond quickly to enquiries. Make finance part of the customer conversation early enough to understand the real budget. Give customers clear information about the vehicle, monthly payments and available options.
We covered some of those points recently when looking at how UK dealers can convert higher used car demand into sales.
It is also worth keeping an eye on supply.
Stronger new car registrations should eventually feed more younger vehicles into the used market. That could improve choice in areas where stock has remained tight following the lower new car volumes seen during and after the pandemic. Auto Trader has previously warned that the age profile of available stock will continue to create gaps in certain parts of the market during 2026.
Dealers that know which gaps affect their own customer base will be better placed to source ahead of demand.
Yes. Current data points to an active UK used car market.
Transactions passed four million during the first half of 2026, August sales increased year on year and Auto Trader now expects the full year to reach around 7.95 million used car transactions.
Cars are also continuing to sell at pace, averaging around 29 days on retailer forecourts during September.
For dealerships, the opportunity sits in matching that demand with the right stock, sensible pricing and finance options suited to a wider range of customers.
Auto Trader forecasts around 7.95 million used car transactions during 2026, which would make it the strongest year for used car sales since 2017.
Yes. SMMT recorded modest growth across the first half of 2026, while Auto Trader reported a 2.6% year-on-year increase in used transactions during August.
Used cars took an average of 29 days to sell in September 2026, although performance varies significantly by model, age, price and fuel type.
Auto Trader reported an average advertised used car price of £17,131 in August 2026. Like-for-like prices were down just 0.1% year on year, showing relatively stable overall pricing.
Higher transaction volumes give dealerships more potential customers to work with. Stock selection, pricing, response times and access to suitable finance still play a major role in turning that demand into completed sales.
Marsh Finance works with UK car dealers to provide flexible near-prime car finance, including HP and PCP, backed by rate-for-risk pricing and experienced underwriting.
