The European Used-Car Industry — Understanding the Playing Field

AUTO1 Group is a Berlin-based digital platform that buys used cars from consumers, wholesales most of them to professional dealers, and retails a growing minority directly to other consumers — all across roughly 30 European countries. To judge AUTO1 you first have to understand the arena it competes in: a vast, old, intensely fragmented, and barely-digitised market where the money is made one car at a time, on margins so thin that scale and cost-per-car decide who wins. This tab builds that mental model from the primary record, then frames the competitive, cyclical, and regulatory forces an investor needs before reading the rest of the report.

The single most important idea: this is not a high-margin software business. It is a physical, principal-trading business — AUTO1 takes title to the cars on its own balance sheet — wrapped in technology. Gross margin at the group level is about 12% [10]. Everything in the industry flows from that fact.

1. The arena in one minute

Sources: AUTO1 Capital Markets Event 2026 [1] [2]; Q4/FY2025 earnings call [3].

Europe's used-car market is worth roughly €700 billion a year, with an additional €100 billion financing pool layered on top [1]. About 27.5 million used cars change hands annually across the continent [3]. To frame the scale: used-car sales account for almost two-thirds of all automotive transactions in Europe — the used market is far larger by unit count than the new-car market [5].

Two structural features define the playing field:

• Extreme fragmentation. There are more than 250,000 used-car dealers in Europe, and the top 20 own less than 6% of the market [2]. No incumbent has scale; the market is a long tail of small local lots. That is the gap a pan-European platform is built to consolidate.
• Barely digitised. Management describes used cars as "the largest vertical with a low online share," still sold "almost exclusively offline" [4]. The structural thesis for the whole sector is a slow migration of these transactions from offline to online — and 77% of consumers say they dislike the current car-buying experience [2].

Against that backdrop, AUTO1's 3.1% share in 2025 — with a stated long-term target of 10% — tells you how early this consolidation still is [3].

2. How the money is actually made: three doors into one platform

A newcomer's first job is to learn the three customer-facing motions and the jargon attached to each. AUTO1 runs one vertically integrated platform with three brands [7]:

• C2B sourcing (consumer-to-business) — the wirkaufendeinauto.de brand. Consumers sell their old car to AUTO1 at a haggle-free price, often dropping it at a nearby branch. This is the supply funnel that feeds everything else.
• B2B wholesale — the "Merchant" segment — AUTO1.com, Europe's #1 online wholesale platform, where 54,000 professional dealers buy cars in digital auctions across 30+ countries [8]. Started in 2013, this is the larger, profitable engine [9].
• B2C retail — the "Retail" segment — Autohero, a direct-to-consumer online used-car store (refurbished cars, fixed prices, home delivery, 21-day returns). Started in 2020, it is the high-growth, still-loss-making disruptor [9].

Three terms you must internalise to read this sector:

Principal vs. marketplace. AUTO1 is a principal trader — it buys the car onto its own balance sheet and resells it, so revenue is the full car price and the company carries inventory and price risk. A marketplace or classifieds business (e.g. Auto Trader) only takes a listing fee and never owns the car. This single distinction explains nearly all the margin differences across the peer group below.

GPU — gross profit per unit. Because every car is a transaction, the industry is run on euros of gross profit per car sold, not on percentage margins. GPU is the master KPI. Add up GPU across cars, subtract cost-per-car, and you have the business.

ASP — average selling price. The average price of the cars traded (roughly €8,000–9,000 in Merchant, higher in Retail). ASP drifts up over time as the fleet ages into more expensive model years [3].

The reason a platform can beat 250,000 local dealers is vertical integration at continental scale: a proprietary dataset of 6+ million transactions feeding AI pricing, 12 production (refurbishment) centres with capacity for 248,000 cars, 170+ logistics centres, and 750+ drop-off branches — the largest cross-border car-logistics network in Europe, built over more than a decade [7] [18]. A car with a weight of one to two tonnes "cannot be conquered by an AI prompt" — the physical network is the moat [10].

The two engines have opposite economics

Source: AUTO1 Capital Markets Event 2026 — Merchant per-unit economics [11] and Retail per-unit economics [12].

This table is the whole industry in miniature. Merchant is a high-volume, low-GPU machine that already makes money per car (€323 of adjusted EBITDA per unit in 2025). Retail carries a far higher GPU (€2,638) but also a far heavier per-car cost base — refurbishment, brand marketing, last-mile delivery — and still loses €410 per car, a loss management is deliberately narrowing each year as scale spreads fixed costs. The long-term targets imply both engines turning into €400–800 of EBITDA per car, which is the entire bull case in one row [14].

3. Why it is a thin-margin, scale-driven business

In 2025 AUTO1 sold 842,000 cars, generated €991 million of gross profit (up 37%), and turned that into €198 million of adjusted EBITDA — an adjusted EBITDA margin of just 2.4% [10]. Group gross profit per unit was €1,172 [10]. On a car selling for several thousand euros, that is a wafer-thin slice — and it is why the industry is so unforgiving: there is no room for sourcing mistakes, mispricing, or logistics waste. The companies that survive are the ones that grind cost-per-car down faster than competitors and attach high-margin extras (financing, warranties) to each sale.

The structural promise is operating leverage: most of the cost base is fixed (refurbishment centres, logistics, technology, brand), so as volume grows, cost-per-car falls and a rising share of each incremental GPU drops to EBITDA. AUTO1's own evidence: gross profit grew 37% while adjusted EBITDA grew 81% in 2025 [10], and management targets a long-term adjusted EBITDA margin of 5% to 9% versus 2.4% today [3]. The whole investment debate is whether that leverage is real or whether thin margins are a permanent feature of trading physical cars.

The clearest way to see the engine working is the multi-year GPU climb — the rising gross profit captured on every car, which comes from better AI pricing, more attached financing, and value-added services:

Source: AUTO1 Capital Markets Event 2026 — Merchant GPU track record [11] and Retail GPU track record [12].

Merchant GPU rose from €749 to €976 over five years (long-term target €1,200+); Retail GPU climbed seven-fold off a tiny base to €2,638 (long-term target €3,000+) [11] [12]. A meaningful and growing slice of GPU now comes from embedded financing — a captive lending layer attached to each car that carries far higher margins than the metal itself, and which management views as the long-term profit unlock [10].

4. Market size, fragmentation, and the offline-to-online runway

How big is the opportunity, really? The market can be sized as a funnel, from the total European car fleet down to the slice a platform can realistically capture:

Source: AUTO1 Capital Markets Event 2026 — Europe-wide sourcing opportunity [16].

Continental Europe has a car parc of ~190 million vehicles; about 24% of owners intend to sell within 12 months (~45m cars), of which roughly 10–15 million are addressable consumer-to-business selling demand annually [16]. On the demand side, AUTO1 frames ~10 million units a year of external dealer-sourcing demand for its wholesale product — of which it captures only 7% today — and a 15-million-unit addressable retail market for Autohero [15] [17]. Whichever lens you use, AUTO1's current penetration is low single digits — the runway is the story.

The offline-to-online shift has been the sector's structural tailwind since the IPO era: at the 2021 listing, management sized the European used-car market at ~€600 billion in 2019, growing at a 5% CAGR to 2025, and emphasised that it remained "highly fragmented and at a very early stage of online penetration" [6]. Five years on, the same fragmentation persists — confirming that consolidation in this industry is a multi-decade, not multi-year, process [2].

5. Where we are in the cycle

Used-car volumes are mature and mildly cyclical — they oscillate in a band rather than grow secularly. Across Europe, annual transactions have moved between roughly 24 and 28 million over a decade:

Source: AUTO1 Capital Markets Event 2026 — European used-car market transactions [2].

The cycle's defining variable is not unit volume but used-car prices, which feed directly into ASP, GPU, and inventory risk. The most instructive recent episode: the 2021–2022 semiconductor shortage throttled new-car production, pushed buyers into the used market, and sent used-car prices sharply higher — a demand surge that drained dealer inventories to about 17% below pre-pandemic levels [19]. That spike inflated GPUs in 2021, then normalised as supply chains healed — visible in the 2022 volume trough above. Today the market is in a stable phase: volumes grew about 1% in 2025, while AUTO1's own ASP rose ~7% as it trades progressively newer, more expensive model years [3]. The key cyclical lesson for an investor: a principal trader's earnings are levered to price, and a sharp downturn in used-car values would compress GPU and create inventory write-down risk even if unit volumes hold.

For 2026, management guides to 940,000 to 1,000,000 group units, €1.1–1.2 billion of gross profit, and €250–275 million of adjusted EBITDA, all funded from a balance sheet with ~€600 million of cash and no corporate debt — inventory is financed through asset-backed securitisation rather than corporate borrowing [20].

6. The competitive landscape

There is no European pure-peer at AUTO1's scale running the identical dual wholesale-plus-retail model — at IPO the company noted it sold "approximately twice as many used cars as its closest peer in the EU" [5]. The useful way to map the field is by business model, because model — not geography — drives the economics. Three archetypes compete for the used-car profit pool:

• Principal online/omnichannel retailers (take title, sell to consumers): Carvana in the US — "the leading e-commerce platform for buying and selling used cars" [22]; CarMax, "the nation's largest retailer of used vehicles" (780,684 retail units) [23]; and Aramis Group in Europe (France/Spain/Belgium/etc.), the closest listed analogue to Autohero, which sold ~119,000 cars to individuals and runs France at "profitability close to 5% EBITDA" [26].
• Wholesale digital marketplaces (mostly fee-based, the AUTO1.com analogue): OPENLANE, "a leading digital marketplace for wholesale used vehicles" with $28.8 billion of GMV across ~1.5 million transactions [24]; and ACV Auctions, a US dealer-to-dealer wholesale marketplace still running operating losses (–$63 million in 2025) [25].
• Classifieds / advertising marketplaces (never touch the car): Auto Trader in the UK, whose strategy is simply to be "the best place to buy and sell a car" as a listings platform [27].

The spectrum of gross margins makes the model differences unmistakable — and explains why AUTO1's ~12% looks low against software but is entirely normal for a principal car trader:

Sources: latest annual filings — Carvana FY2025 [22]; CarMax FY2026 [23]; Aramis FY2025 [26]; Auto Trader FY2025 [27]; margins as reported.

The four principal traders cluster at 10–21% gross margin — they buy and resell metal. Auto Trader, which only sells listings and never owns a car, earns ~77% gross margin and ~62% operating margin [27]. That gap is the central trade-off of the industry: principal models capture the whole transaction (and its risk) but on thin margins; asset-light models earn fat margins but cede the transaction itself. AUTO1's bet is that owning the physical pipe — sourcing, pricing, refurbishment, logistics, financing — builds a deeper, more defensible position than a listings page, even at one-sixth the gross margin.

Sources: latest reported annual filings — AUTO1 FY2025 [10]; Carvana FY2025 [22]; CarMax FY2026 [23]; Aramis FY2025 [26]; OPENLANE FY2025 [24]; Auto Trader FY2025 [27]. Revenue shown in each company's reporting currency; OPENLANE and Auto Trader revenue is fee/advertising revenue, not vehicle value, so gross margin is not comparable to the principal traders.

A note on AI as a competitive force, since investors will ask: management argues large language models and AI-driven search may erode classifieds traffic — the first search touch-point — but cannot replicate a principal trader's physical network, balance sheet, and proprietary transaction-pricing data. As of the latest call, management reports no new entrants attacking the sourcing or retail side [10]. The competitive risk for the classifieds model may be greater than for the principal model.

7. Regulation and structural risks

The European used-car industry is lightly regulated relative to financial or healthcare sectors, but exposed to a mosaic of local rules that shift the goalposts country by country. AUTO1's own risk reporting frames the key channels [21]:

• Vehicle-type / emissions policy. Management explicitly flags that new regulations "can lead to a decline in certain vehicle types, including those in our inventory," which "can negatively affect our margins" [21]. Diesel bans, low-emission zones, and the EV transition can abruptly reprice whole tranches of the used fleet a trader holds — the most material regulatory risk in this business.
• Cross-border friction. Operating across 30+ countries means VAT, registration, and consumer-protection regimes differ in every market; a platform's pan-European logistics has to absorb that paperwork as a cost of doing business.
• Financing → conduct regulation. As AUTO1's captive lending arm grows, it brings the business into anti-money-laundering and data-protection compliance, and consumer-credit conduct rules — a heavier regulatory layer than pure car trading [21].
• Demand-side friction (not regulation, but structural). A persistent brake on the offline-to-online thesis is that some buyers still will not purchase a car they cannot see and test-drive in person; traditional dealers retain a "relatively strong position" in retail [21]. This is why online penetration has climbed slowly despite a decade of investment.

Net assessment: regulatory risk is medium — no single rule threatens the model, but the EV/emissions transition and the financing build-out are live, margin-relevant policy exposures worth monitoring.

8. Watchlist — the signals that would change the industry view

Sources: AUTO1 Q4/FY2025 earnings call [3] [10]; Capital Markets Event 2026 GPU track record [11] [12]; FY2021 industry conditions [19].

The bottom line for a newcomer. The European used-car industry is a €700bn, fragmented, mostly-offline market in the early innings of digitisation [1]. It rewards whoever builds the lowest-cost, largest-scale, vertically integrated machine for moving cars — but it does so on per-car margins thin enough that execution, pricing accuracy, and cost discipline are everything. The structural runway is real and decades long; the day-to-day reality is a capital-intensive, cyclically price-exposed, low-margin trading business. Hold both truths at once, and the rest of this report will read clearly.
