How 1 Crore+ Car Inspections Have Shaped CARS24’s Quality Benchmarks

It is a well-known practice that when someone performs a job, there is a high chance of making mistakes. But what if that same job has been performed over thousands or lakhs of times? Yes, you are guessing it right? The probability of making a mistake would drastically reduce, and perfection becomes unconditional.

This same story has been repeated by us in our inspection service. With the car health data and experience of over 1 crore car inspections since 2015, we have redefined the quality benchmarks in car inspection. CARS24 used car inspections leave no stone unturned to bring up the real health of a car.

We ensure that your car is evaluated by expert car inspectors and get a standardised digital health report. Gone are the days when dealers or individual car buyers forced the car price down by calling up ghost flaws. Let’s understand how vast experience and massive used car health data have shaped inspection quality in the used car industry in India.

Building a Library of Used Car Health Data

In the traditional market, a mechanic’s expertise is limited to the number of cars they have physically touched or test-driven. This number could be a few hundred or a thousand over a career. While valuable, this is still a limited sample size when compared to CARS24’s data pool of 1 crore+ used car inspections, which allows us to see the big picture.

When we perform an inspection of a car, we compare it against millions of similar data points. This volume has allowed us to move beyond general checks to model-specific intelligence. Moreover, we have identified that certain engine mounts on a specific 2017 hatchback might show premature wear after 40,000 km, or that a particular SUV’s suspension behaves differently in the pothole-heavy terrains of one state compared to the highways of another.

This is how massive datasets help us form our quality benchmarks in used car inspections.

The Science of Predictive Diagnostics

Our data-driven approach allows for something called Predictive Diagnostics. Our system can flag a potential issue before it is even visible to the naked eye. It would not have been made possible without our store datasets on the health of millions of pre-owned cars.

• Model-Specific Intel - Our systems now know exactly which parts are likely to wear out first in specific models based on their age and mileage. For example, if data shows a high failure rate for a specific sensor in a 5-year-old sedan, our inspectors are automatically prompted to conduct a deep dive into that particular component.
• Regional Wear & Tear - India’s climate is diverse, and thus, climate-related deterioration cannot be the same for cars in different regions. For example, a car used in the humid, salt-heavy air of coastal Mumbai faces a higher risk of underbody corrosion than a car in the dry heat of Delhi. Our 1 crore+ database accounts for these geographic variables, ensuring that a car in one region is held to a benchmark that respects its environment.

Training the AI Algorithms with 10 Lakh Transactions

Every single car inspection we conduct feeds into our AI-powered pricing engine. This used car value checker has been trained on over 10 lakh actual used car transactions. Therefore, our system is able to bridge the gap between a car’s physical health and its true market value.

Our AI algorithms are programmed in such a way that they can distinguish between a car that is accidental and has structural damage and one that simply has panel repainting due to minor scratches. This distinction is crucial for fair valuation.

Moreover, as electric and hybrid cars enter the second-hand market, our 1 Crore database updates these benchmarks in real-time. In addition to these, we are currently building the industry’s first comprehensive quality benchmarks for used electric vehicles, focusing on battery health and motor efficiency.

Shared Data for Total Trust

At the heart of our process is the CarTruth inspection report. We believe that transparency is the only way to build long-term trust in the used car industry.

• 300+ Point Checklist - Every car undergoes an exhaustive check across all major categories, including Structural Integrity, Engine & Transmission, Steering and Suspension, ECU, Electricals, and more.
• No Hidden Findings - We share the exact same data with the seller that we provide to our bidders. If our scanners detect an ECU fault code or a repainted panel, all of them are documented with photos.
• PDI as a Service - As our inspection standards are now considered the gold standard in the industry, we offer them as Pre-Delivery Inspection (PDI) services even for cars being bought elsewhere. This proves that our benchmarks are independent and serve as a "Third-Party" seal of quality.

Conclusion

At the end, when we talk about our inspection quality benchmarks, we aren't talking about a single car evaluator’s "good day" or a dealer’s "gut feeling." We are talking about mathematical and technical certainty built over a decade of rigorous data collection.

1 Crore+ inspections have allowed us to move the conversation from "I think this car is good" to "The data proves this car is good." By leveraging the power of scale, we ensure that every seller receives a price that reflects the true market worth, and every buyer drives home a vehicle that is safe, reliable, and road-ready.
