Technology rebuilds trust & transparency in Australia’s used-car market

Australia's used-car sector is undergoing substantial change as technology introduces new levels of transparency and consistency to transactions. Processes powered by data analytics, artificial intelligence and digitisation are helping to address long-standing issues of trust that have impacted the reputation of the industry.

Market transformation

Pricing in the used-car market was historically subjective, often driven by perception and negotiation rather than objective evidence. Recent advances in AI and machine learning now allow businesses to analyse thousands of listings, tracking vehicle mileage, condition, and historic sale rates to determine market-based valuations. These data-driven methods are creating more reliable and uniform pricing structures for both buyers and sellers.

AI-powered models also monitor demand signals and depreciation trends by vehicle model. Rather than relying on instincts or expectations, pricing engines such as those at CARS24 reflect real-world transaction data. "When everyone is looking at the same evidence, fairness naturally follows," said Aman Shienh, Head of Business, CARS24.

Digital quality assurance

Technology is also overhauling quality control processes. Digital inspections, often involving hundreds of checks on mechanical, electrical and visual features, provide detailed records for each vehicle that passes through a platform's system. These details, stored and verified online, are accessible to both internal teams and prospective buyers, introducing a single, consistent source of truth.

Photographic documentation and diagnostics support each inspection, increasing visibility into the condition of individual cars.

Digitised workflows also connect the stages of refurbishment, storage and delivery. This provides traceability across each stage of the used-vehicle lifecycle, allowing for better accountability and transparency.

Industry-wide change

These developments are not confined to one company. The broader Australian market has witnessed a rise in digital platforms and standardised inspection systems. Online used-car sales are increasing by over 15 percent a year, according to recent research from Expert Market Research and Mordor Intelligence. This reflects a growing consumer preference for digital sales channels and greater reliance on verified information during the purchase process.

The shift addresses information gaps that have historically undermined confidence in the sector-an issue identified by economists such as George Akerlof in his work on "market for lemons" theory. As buy-and-sell platforms invest in automation and data integration, the knowledge imbalance between buyers and sellers is narrowing, and regulatory compliance is becoming more manageable.

Focus on accountability

While digital systems provide the tools for transparency, their effectiveness relies on organisations backing them with clear service guarantees. CARS24, for example, has introduced a seven-day return policy and offers a warranty with unlimited claims up to the vehicle's value. These measures are supported by digital tracking and verification processes that follow each car from inspection through to sale and post-purchase support.

"Those promises are only possible because every car's data is tracked and verified throughout the process. When information is reliable, trust stops being an aspiration and becomes a deliverable," said Shienh.

Future integration

Australia's used-car sector, valued at over AUD $118 billion annually, is among the most digitised segments of the retail industry. The next phase of digital transformation is likely to involve deeper links between inspection, logistics and finance, further embedding transparency in operations and service delivery.

Shienh said, "Efficiency is important, but integrity is what scales. Technology isn't just automating the used-car trade, it's rebuilding confidence in it."
