This is How CARS24 Maintains Inspection Consistency Across 220+ Cities

As you have experienced in the offline used car markets, the quality of inspection has always been a localised concept. If you were buying a car in a metro city like Delhi, Mumbai, or Bangalore, you might get access to specialised workshops. However, if you reside in a Tier-2 or Tier-3 city, you remain at the mercy of the local mechanic’s "gut feeling."

This is what we call “Pincode Bias." Due to this, the definition of a "good car" changes every 50 kilometres, creating a massive trust deficit for buyers and sellers alike.

At CARS24, we set out to solve this geographic lottery in car inspections. Today, we operate across 220+ cities, from the busiest metros to the furthest corners of the country. Whether a car is being inspected in the heart of Mumbai or a quiet suburb in Bihar, the result will always be a standardised and data-backed report that meets a single national benchmark.

Let’s understand how we are able to maintain absolute inspection consistency across India’s diverse landscape.

Unified Digital Inspection Protocol

If you want consistency, nothing can be left to human memory. To ensure that every car goes through a standard checklist, we have developed our own proprietary inspection app. This app is the primary tool for our 1,500+ trained experts who perform inspections on a daily basis. The app has been designed with strict "Mandatory Progression" logic. Therefore, an inspector cannot record the engine health without first completing the structural integrity checks.

In the offline market, a mechanic might skip a difficult-to-reach component and later forget it. However, at CARS24, our strict inspection protocol prevents skipping any step.

In addition to this, every checkpoint requires a specific input, often a high-resolution photograph or a data reading, which is instantly uploaded to our central servers. This digital leash ensures that "The CARS24 Way" is followed to the letter, whether the inspection is happening in a high-tech hub or at the customer's home.

Centralised Inspection Training

Before any of our car experts are sent for inspection duties, we provide all of them with a formal centralised training program. Every CARS24 inspector, whether they are based in Kochi or Kanpur, goes through the same centralised training program. This curriculum is built on the insights gathered from our 1 Crore+ (10 million+) previous inspections.

• The Golden Standard - Our training teaches car inspectors how to identify "Model-Specific" wear patterns.
• Continuous Upskilling - As new cars enter the market (including the latest EVs and hybrids), our training modules are updated centrally and pushed to every inspector's tablet simultaneously.
• Calibration - We periodically perform shadow inspections where senior auditors verify the findings of local inspectors to ensure their rating of a dent or an engine data aligns with our national quality floor.

Removing Subjectivity with High-Tech Tools

When it comes to opinions, humans are best at it. Even if they are not supposed to present their opinions at the table, they will do it even if it is unconscious. Subsequently, these opinions also trickle down in the offline car inspections. At CARS24, we have eliminated human opinions by adding a layer of modern tools and their readings.

Regardless of the city or the state, every CARS24 used car inspection kit includes OBD-II scanners and Paint Thickness Gauges. OBD-II devices are used to connect with the car’s ECU to get all the hidden data, sensor issues, error codes, etc. Paint thickness gauges, on the other hand, are used for checking the repainted panels, which most sellers try to hide.

Centralised Inspection Quality Audit

To manage a network as vast as 220+ cities, we maintain a Centralised Quality Audit team. Every report generated in the field is not immediately termed as final. A significant percentage of reports are flagged for manual review by our central audit team.

The quality audit team cross-references the inspector’s written notes with the uploaded photos. If an inspector claims "No accidental damage" but a photo shows a slightly misaligned apron, the report is sent back for correction.

Our AI systems scan thousands of reports daily to look for "Anomalies." For example, if an inspector in a specific city is consistently reporting "Excellent" engine health for cars over 1 lakh kilometres, the system flags it for a quality audit to ensure standards aren't slipping.

CARS24 National Consistency Matrix

Balancing Regionality with Standardisation

When it comes to car inspection, we can set certain standards, but there has to be a layer of regionality as well. Because a car’s condition in Mumbai and Delhi would be quite different due to the weather conditions.

This is exactly where our intelligence from 1 crore+ inspections comes in handy. Our database of 1 Crore+ inspections allows us to build "Regional Profiles" for different cars in different regions. We know that a car in a coastal city like Vizag requires a more intensive check for underbody rust than a car in the drier city of Jaipur.

As we set all these Environmental Flags into our 300-point checklist, we ensure that the inspection is consistent in its rigour, even if the focus areas shift slightly based on the geography.

Final Thoughts

At the end, we would like to assert to the fact that the scale of 220+ cities could have been a liability for quality control. Instead, at CARS24, we have turned it into our greatest strength by combining a strict digital protocol, high-tech diagnostic tools, and a centralised audit system.

Subsequently, the inspection report is the collective intelligence of 1,500 experts, 10 years of data, and a technological framework designed to ensure that the truth remains the same, no matter where you are in India.
