Buying a used (second-hand) car can save you a lot of money compared to buying a new car. A new car loses 15-20% of its value in the first year and about 50% in 5 years. This means that a 4-5 year old car can give you excellent value, if you buy it wisely.
But many people avoid buying a used car due to the fear of fraud and scams by dealers. If you fall into this category, this guide will help you buy a used car in India scam-free and stress-free.
Step 1: (Pre-inspection) Do your research before meeting the car seller.
- Know the common problems of the car model.
- Some cars have minor “non-issues” (e.g., Hyundai Santro headlight leaks, Maruti Dzire tail lights).
- Other cars have serious problems (e.g., Renault Kwid oil sump cracks). Avoid cars with known engine-related defects. 🔴
- Research the internet or owner forums to know what problems to expect.
Find the right market price (Realistic Price Range)
- Check 5-10 listings on online marketplaces for the same model/year.
- Average the prices and deduct ₹50,000–₹1 lakh (dealers usually inflate).
- Knowing the actual price prevents overpaying.
Step 2: Check vehicle documents

Service history
- Take the car to an Authorised Service Centre (ASC) – Check if the car was regularly serviced at an Authorised Service Centre (ASC).
- It helps to check if the odometer is correct. Gaps in service history = possible odometer tampering 🔴.
- You can use online services like Car24, Car Info, CarDekho (paid) to get the service history.
Registration Certificate (RC).
- Check the owner’s name – The owner’s name should match.
- The RC should be clear (no hypothecation mentioned).
- If a loan has been taken, make sure that NOC is available and no insurance is pending.
Insurance and claim history
- Check past claims to find accidents.
- Check pending challans and legal issues.
- Check challans on your state RTO websites (parivahan.gov.in). Check
- Avoid cars with large fines or legal court cases.
Step 3: Inspect the engine and parts

Basic engine check.
Even if you are not a mechanic, you can do a simple check.
Use the dipstick: Check the oil
- Gasoline car oil should be golden/brown (not black 🔴).
- Diesel car oil is usually black – this is normal 🟢.
Check for leaks.
- Park on a clean floor, drive for 10 minutes, check for oil/coolant leaks.
- Check for noise and smoke.
- Start the engine, listen carefully.
- Strange hissing, knocking, or colored smoke : (don’t buy)🔴.
Parts and replacements
Make sure the replacement parts are OEM or from a reputable brand (not cheap aftermarket).
Use an OBD2 scanner.
- You can also do the online purchase yourself, plug in to check the error code.
- You can also get it done with the help of an expert.
Check the battery age, if it is more than 2 years old? You can reduce the price.
Step 4: Inspect the body and exterior

Paint and panels
- Minor scratches/dents are fine.
- Mismatched paint = accident repair 🔴.
- Cracks filled with putty or bulging paint, which could be the cause of a major accident. Avoid 🔴.
Check for rust
- Use a selfie stick + phone camera to inspect the underbody.
- Heavy rust : Avoid 🔴.
- Check for accident marks.
- Check for factory spot-welding marks (must be original).
- All glass panels should be the same code/year, check.
Check tires
Negotiate the price if there are high-wear tires.
Step 5: Inspect the interior and electronics
- Check the condition of the seats, dashboard, buttons, and switches.
- Make sure the AC, lights, wipers, and infotainment work.
- Minor wear and tear is normal, but major electronic failures : Don’t buy 🔴.
Step 6: Take a long test drive (20-30 minutes)
Check the engine and gearbox
Check that there are no unusual noises.
Hard clutch or loose gear shift :🟠 (Repairable).
Brakes : The car should stop straight, no jerking.
Suspension : No loud bangs or thumps.
Steering : The car should not turn left/right on a straight road.
Step 7: Decide on the Red/Orange/Green Flags to Use
🟢Green Flag : Totally Fine (Minor issues (scratches, worn tires)).
🟠Orange Flag : Fixable issues (clutch, alignment).
🔴Red Flag : Don’t Buy (Engine noise, oil leaks, accident damage, legal disputes: Avoid buying).
Step 8: Final Considerations.
- Don’t worry too much about E20 fuel compatibility for older cars.
- A well-maintained car that is 5-7 years old will still last another 6-7 years.
- Focus on document clarity, accident-free condition, and proper maintenance.
Quick Red Flag 🔴(Avoid this car)
🔴 Accident-prone (repainted doors/roof, replaced glass, welding marks)
🔴 Odometer tampering (irregular service history, sudden mileage drop)
🔴 Engine leaks, strange noises, or colored smoke
🔴 Fake or unclear documents (loan hypothecation, no NOC, outstanding bills)
🔴 Underbody rust
Follow the quick checklist before buying.
- Check service history and odometer
- Check RC, insurance, NOC, challan
- Inspect engine oil, leaks, OBD errors
- Re-check body for paint, rust, accident signs
- Inspect tires, interior, electronics
- Take a long test drive
- Make a decision with the flag system (green/orange/red).
