Carsales is the better platformer, for (REA)l.
REA Group and CAR Group both score 7.8/10 with wide moats. REA reports 35.8% ROIC versus CAR at 9%, but CAR carries \.2B of goodwill that distorts the number. Organic ROIC is above 50%.
REA Group and CAR Group are the two highest-quality marketplace businesses on the ASX. Both hold #1 positions in their verticals, both generate high margins from asset-light platforms, and both score 7.8/10 on our business quality framework.
On the surface, REA looks like the stronger business. Higher margins, higher returns on capital, a more dominant market position in its core geography. But one number in the comparison table is not what it appears, and understanding why changes how you think about both companies.
The Comparison
| Metric | REA Group (REA) | CAR Group (CAR) |
|---|---|---|
| Rating | HOLD | HOLD |
| Price | A$166.42 | A$26.89 |
| Fair Value | A$128.00 | A$25.04 |
| Gap | -23% (overvalued) | -7% (approx. fair) |
| Quality Score | 7.8 / 10 | 7.8 / 10 |
| Moat | Wide (8-12 years) | Wide (7-10 years) |
| EBITDA Margin | 62% | 54% |
| FCF Conversion | 89% | 95% |
| ROIC | 35.8% | 9.0% |
| Revenue Growth (H1 FY26) | +5% | +12% CC |
REA's operating metrics are ahead on most lines. 62% EBITDA margins versus 54%, a 35.8% return on invested capital versus 9%, and a longer estimated moat duration. These are the numbers that justify the premium multiple the market assigns to REA.
CAR's advantage is growth runway. REA's revenue growth has decelerated from 15% in FY25 to 5% in H1 FY26 as yield increases approach structural limits (cumulative 40-50% over the past decade, Premiere+ penetration at 75-80%). CAR has LatAm growing at 23% in constant currency with roughly half the Brazilian dealer market still offline, giving it 3-5 years of structural double-digit growth before base effects compress the rate. REA needs new product categories to re-accelerate. CAR just needs more of Brazil to come online.
Valuation
Despite REA's stronger current metrics, the valuation picture favours CAR.
REA at A$166 trades 23% above our fair value of A$128. Every combination of terminal growth rate and discount rate in our sensitivity analysis produces a fair value below the current price. The market is pricing in sustained double-digit yield growth, 62%+ margins indefinitely, and zero probability of any downside.
CAR at A$26.89 trades within a few percent of our probability-weighted fair value of A$25.04. The risk is symmetric from here: +33% in a bull case if LatAm sustains and rates decline, versus -33% in a bear case if recession hits and LatAm decelerates. The market appears to have the growth-versus-risk tradeoff roughly right at current levels.
Two businesses of equivalent quality, but very different entry points.
The ROIC Number That Deserves a Second Look
The widest gap in the comparison table is return on invested capital: 35.8% for REA versus 9.0% for CAR. On the surface, that looks like REA is creating substantial value for shareholders while CAR is barely covering its cost of capital (WACC of 9.0%). For an investor screening on capital efficiency, CAR would get filtered out.
That 9% figure is misleading.
CAR carries $4.2 billion of acquired goodwill on its balance sheet from three international acquisitions: Encar in South Korea, Webmotors in Brazil, and Trader Interactive in the United States. Goodwill is an accounting asset that represents the premium paid above the net tangible assets of the acquired businesses. It sits on the balance sheet indefinitely and inflates the capital base that ROIC is measured against.
The underlying operating assets of CAR's business (the platforms, the technology, the dealer relationships) require very little capital to run. The company generates A$1.2 billion in revenue from roughly A$20 million of property, plant, and equipment. When you strip out the goodwill and measure returns on the actual operating capital deployed, CAR's organic ROIC is above 50%, which puts it in the same category as REA.
The distinction matters because ROIC measured on total capital (including goodwill) answers a different question than ROIC on operating assets. Total capital ROIC tells you whether the acquisition strategy has created value. Operating ROIC tells you whether the underlying businesses have strong economics. For CAR, the answers diverge: the businesses are excellent, but the jury is still out on whether the prices paid for them were justified.
What the Goodwill Actually Represents
CAR's international expansion was a deliberate strategy to build a portfolio of #1 marketplace positions at different stages of maturity. Australia is the cash cow (60% EBITDA margins, mature market). South Korea (Encar) is mid-growth. Brazil (Webmotors) is early-to-mid growth with the longest runway. The US (Trader Interactive) focuses on non-auto verticals.
The $4.2 billion of goodwill is the cost of assembling that portfolio. Whether it was money well spent comes down to one question: can LatAm margins converge toward Australian levels over time?
Today, Webmotors operates at roughly 38% EBITDA margins compared to 60% in Australia. If Brazil can reach 45-50% as the dealer market digitises and scale effects compound, CAR's group ROIC on total capital should improve toward 12%+ and the acquisitions will have justified their price tags. If LatAm margins plateau in the high 30s, CAR will remain a business earning approximately its cost of capital despite holding monopoly positions in four geographies, which would be a structural concern regardless of revenue growth.
Our analysis identified this as the single assumption that would most change the valuation. If LatAm margins reach Australian levels, the group margin ceiling lifts from 56% to 58-60%, adding A$4-5 per share to fair value. That is a larger impact than changes to WACC or terminal growth, which are typically the parameters investors focus on.
What This Means for the REA Comparison
REA does not have this ambiguity. Its capital has been deployed organically over decades, and the 35.8% ROIC reflects genuine value creation on the actual capital in the business. There is no goodwill distortion, no acquisition strategy to evaluate, no margin convergence question to resolve. For investors who want clean capital efficiency metrics, REA is the simpler story.
But REA also does not have CAR's growth optionality. REA's growth depends on raising prices further in a market where cumulative increases are approaching resistance levels. CAR's growth depends on continued digitisation of dealer markets in economies where online penetration is still early. These are fundamentally different types of growth: pricing power in a mature market versus structural adoption in an emerging one.
At current prices, REA asks you to pay a 23% premium for cleaner metrics and a more dominant single-market position. CAR asks you to pay approximately fair value for a more complex business with a longer growth runway and an unresolved capital efficiency question. Neither is a BUY today, but they represent different risk profiles for investors weighing marketplace exposure on the ASX.
