Sellers are not always dishonest, but they are always selling. The useful checks on a used car are the ones that do not depend on what you are told — government records, insurance documents, and the physical car itself. Almost all of them are free and take minutes.
Start with the Vahan record
The national vehicle database at parivahan.gov.in will return a vehicle's core record from its registration number. Do this before you travel to see the car, not after you have fallen for it.
What it tells you, and what to do with each field:
| Field | What to check |
|---|---|
| Make, model, variant, fuel | Must match the car being advertised. A mismatch means the listing is wrong or the number belongs to another vehicle. |
| Date of first registration | This — not the model year — determines the car's legal age, its remaining life under any age restriction, and when re-registration falls due. |
| Registering authority | Tells you which RTO holds the file, which matters for transfer and for NOC if you are moving states. |
| Tax status / tax paid upto | Arrears follow the vehicle. If tax is not paid up to date, settle who clears it before you agree a price. |
| Fitness / RC validity | Private cars are normally registered for 15 years, after which renewal and a fitness test are required. |
| Insurance validity | An expired policy is both a legal problem and a sign of neglect. |
| Hypothecation | If a financier is named, a loan interest exists on the record. See below. |
Hypothecation: the one that costs people money
If the car was bought on finance, the lender's name appears on the RC. When the loan is cleared, the owner is supposed to obtain an NOC from the financier and file Form 35 with the RTO to remove the entry. Plenty of owners never bother.
That leaves you buying a car with a live lender interest recorded against it. The transfer will stall at the RTO, and in the worst case you have paid for a vehicle someone else has a claim over. The fix is simple but it must happen before money changes hands: ask the seller to produce the financier's NOC and the completed Form 35, and confirm the entry has been removed on the Vahan record.
Pending challans
Traffic challans attach to the registration number. Once the car is yours, unpaid ones are effectively yours too, and in some states they will block the transfer itself. Check the e-challan status for the registration number and make clearing any outstanding ones a written condition of the sale.
Insurance and claim history
The insurance documents are the single most revealing thing a seller can hand you, which is why some are reluctant to.
- The policy itself. Check it is current, and check whether it is comprehensive or third-party only. Long-term third-party-only cover on a newer car often means the owner stopped caring about the vehicle's condition.
- No Claim Bonus. A high NCB — 35% and above — means several consecutive claim-free years, which is genuine evidence of an uneventful history. An NCB of zero on an older car means claims have been made.
- Claim history. Ask directly whether any claim has been made and for what. A total loss or constructive total loss entry is the most important red flag in the entire process: it means an insurer judged the car uneconomic to repair, and it is the usual fingerprint of flood submersion or a severe accident. Cars written off in this way are sometimes repaired and returned to the market.
Match the numbers physically
Paperwork that describes a different car is the beginning of a serious problem. Before paying anything, find the chassis number stamped on the vehicle — commonly on the firewall in the engine bay, under the driver's seat, or beneath a carpet flap — and the engine number on the block, and check both character by character against the RC.
Look at the stamping itself as well as the digits. Uneven spacing, inconsistent depth, filed surfaces or a plate that looks like it has been disturbed all warrant walking away and, frankly, not continuing the conversation.
Read the service history properly
A service book is only useful if you read it as a sequence rather than a stack of stamps.
- Do the odometer readings climb steadily, or is there a jump or a reversal?
- Are there multi-year gaps? A car serviced regularly for four years and then not at all for two has usually had an owner who stopped spending on it.
- Do the big-ticket items appear — timing belt or chain at the specified interval, clutch, suspension overhaul, AC service? On an older car, their absence is a forecast of your costs.
- Do the stamps come from plausible workshops, or do several look identical and freshly applied?
For cars still within the manufacturer's period, many brands can pull the full digital service history from the VIN at an authorised workshop. It is worth asking.
Ownership count
The RC records how many owners the vehicle has had. Fewer is generally better, but the pattern matters more than the count: three owners over ten years is unremarkable, whereas three owners in two years usually means each of them found something they did not like.
Local factors worth checking
Some checks only matter depending on where the car has lived, and they can be decisive:
- Delhi NCR enforces vehicle age limits — 10 years for diesel and 15 for petrol. Calculate remaining legal life from the date of first registration before valuing any car in the region.
- Karnataka charges high lifetime road tax, and bringing an out-of-state car in permanently can be expensive.
- Kerala similarly levies substantial one-time tax.
- Flood-prone markets — Chennai, Mumbai, Kochi, Surat, Vijayawada, Patna — justify a harder look at claim history.
Our city pages set out what applies locally; start from the Chennai, Bangalore or Delhi pages and work from there.
The order to do this in
- Vahan check from the registration number, before you travel.
- Challan check on the same number.
- Physical inspection and test drive — see the inspection checklist.
- Insurance policy and claim history from the seller.
- Service book read as a sequence.
- Chassis and engine numbers matched against the RC.
- Hypothecation cleared, if any.
- Only then, price and paperwork.
