Why Have Used Car Prices Increased?
Used car prices have become a topic of everyday conversation — not just in trade circles, but around kitchen tables and office breakrooms. As of May 2025, the average price of a used car in the UK stands at £16,825, according to Auto Trader’s Retail Price Index. This seemingly unremarkable figure masks a far more complex narrative.
Behind the headline lies a confluence of economic turbulence, global supply chain fragility, and evolving consumer behaviour that continues to reshape the used vehicle landscape.
A Surge in Consumer Demand
Consumer demand is the fulcrum upon which used car pricing pivots. Following the easing of pandemic restrictions, the market was injected with pent-up enthusiasm. Families sought alternatives to public transport amid health concerns, and many first-time buyers — once content with ride-shares — opted to purchase vehicles outright.
Demand for older vehicles, in particular, has seen pronounced growth: a 4.5% YoY increase for 5–10-year-old models and an even more impressive 10.4% rise for cars over 10 years old. This consumer appetite has continued to simmer well into 2025, propping up used car prices.
Supply Chain Disruptions and Component Shortages
The global semiconductor shortage cannot be overstated. Microchips are central to modern automotive electronics and have been in drastically short supply since 2020. This scarcity crippled new car production, forcing consumers to divert attention to the second-hand market.
Compounding the crisis is Ukraine’s critical role in manufacturing wire harnesses — intricate networks of cables found in every car. The war has throttled production across 17 Ukrainian factories, hitting European automakers like BMW, Audi, and Mercedes-Benz particularly hard. With new cars bottlenecked at the production stage, used vehicles filled the vacuum.
Inflation and Escalating Production Costs
Inflation remains an omnipresent shadow across all consumer markets, and automotive manufacturing is no exception. In the UK, production costs have been amplified by some of the highest energy prices in Europe. Mid-2022 saw carmakers shoulder an additional £90 million in energy costs alone.
This inflationary pressure has fed directly into both new and used car pricing. Although newer vehicles faced the brunt of this inflation, the ripple effects inevitably pushed up the value of their older counterparts.
Seasonal Trends and Market Cyclicality
Used car prices often fluctuate in tandem with the calendar. Historically, May has seen modest price dips following April peaks — a seasonal quirk observed annually since 2011, barring pandemic years. In May 2025, prices softened by -0.7% MoM, consistent with this long-term pattern.
However, these changes are superficial compared to broader YoY trends. After a prolonged period of depreciation, prices have plateaued. This flatlining may seem benign, but it reflects a market in careful balance, buoyed by steady demand and constrained supply.
Age-Based Vehicle Demand Shifts
A granular look into age cohorts reveals diverging trajectories. Older used vehicles — particularly those aged 5–10 and 10+ years — are not only in high demand but also appreciating. These models are more accessible to budget-conscious buyers and come with the benefit of lower upfront costs.
In contrast, newer used cars (1–3 and 3–5 years old) are seeing reduced interest. Their higher price tags, combined with newer models entering the market, have eroded their value proposition. This age-based polarity exemplifies the market’s growing sophistication and shifting buyer priorities.
Electric Vehicles and Fuel-Type Dynamics
Nowhere is this nuance more pronounced than in the electric vehicle (EV) segment. Once prohibitively expensive, used EVs are becoming increasingly attractive thanks to consistent price declines. The average used EV now costs £24,370 — down -7.4% YoY. Surprisingly, a 3–5-year-old electric vehicle is currently cheaper than its petrol equivalent.
Petrol and diesel, long the stalwarts of British roads, are waning in popularity. Diesel new car regristrations, in particular, has plummeted by nearly 15.5% YoY. Meanwhile, hybrids and plug-in hybrids are enjoying a renaissance (25% and 50% increase in regristrations), with double-digit demand growth. The fuel-type dichotomy is redrawing the used car landscape with unprecedented speed.
Dealer Inventory and Retail Type Disparities
Not all sellers are navigating the market with equal ease. Independent retailers — those who typically stock older, more affordable vehicles — have thrived, seeing a 4.2% YoY increase in sales. Their ability to align with consumer budgets gives them a competitive edge.
Conversely, franchised dealerships are contending with inventory challenges. The return of 1–3-year-old cars, often more expensive, coincides with a shortage of 3–5-year-old stock — their usual bread and butter. Additionally, competition from brand-new models places downward pressure on their margins.
Brexit Tariffs and Regulatory Implications
Brexit continues to exert gravitational pull on the automotive sector. New rules stipulate that electric vehicles must be composed of at least 45% UK or EU-sourced parts to avoid a 10% tariff. For battery cells and packs, that threshold climbs as high as 60%.
This regulatory burden arrives at a time when manufacturers are already grappling with supply shortages. The additional cost of compliance is often passed on to consumers — either in the form of higher prices or reduced vehicle availability.
Financial Strain: Interest Rates and Financing
A less visible, but equally potent force, is the cost of credit. Financing remains the dominant method of purchasing used cars, yet interest rates now hover at 4.25%. It has started to decrease since a huge spike at the beginning of 2022.
This increase is pricing many consumers out of the market or forcing them to settle for older, less expensive models. Even as headline prices remain stable, the total cost of ownership has grown, reinforcing the perception of used vehicles as a costly proposition.
What Happens if You Need to Buy a Used Car?
The ascent of used car prices is not driven by a singular cause but by several interconnected pressures, from geopolitics to consumer psychology. While the market has shown signs of stabilisation in recent months, it remains delicately poised. Supply shortages, evolving preferences, and economic headwinds suggest that volatility is far from over.
