How to correctly interpret a vehicle history report
Find out how to analyse the mileage, damage, photos, service history, features and other information from a vehicle report.

A report should be analysed as a whole
A vehicle history report should not be interpreted based only on a favourable result or a single warning.
A recorded damage event does not automatically mean that the car should be avoided. At the same time, the absence of damage records does not guarantee that the vehicle has never been damaged or repaired.
To reach an informed conclusion, you need to compare all the available information:
the vehicle’s identity;
the technical specifications;
the factory-installed equipment;
the mileage;
the service history;
the damage history;
previous photographs;
commercial use;
theft records;
recalls;
ITP roadworthiness inspection and RCA insurance information;
the estimated market value.
The report helps you identify risks and discrepancies before viewing the car. The final decision should also be based on checking the documents and completing a technical inspection.
Check the vehicle’s identity first
Start by comparing the information in the report with the advertisement and the car’s documents.
Check:
the VIN;
the make;
the model;
the year of manufacture;
the date of first registration;
the body type;
the engine;
the fuel type;
the transmission;
the power output;
the engine capacity;
the colour.
If the report identifies a different model, engine, or body type, ask for an explanation before proceeding.
Some differences may result from an error in the advertisement or confusion between the year of manufacture and the year of first registration. However, the VIN must match across all documents and the markings on the car.
Compare the specifications with the advertisement
Sellers may enter certain information incorrectly or use a general description for a similar version.
Compare the technical information in the report with:
the advertisement;
the registration certificate;
the vehicle identity card;
the vehicle’s appearance;
the information provided by the seller.
Differences in power output, transmission, engine, or body type can affect the car’s value and running costs.
Do not assume that every discrepancy indicates fraud, but clarify all important differences before paying.
Check the factory-installed equipment
The equipment list helps you verify the vehicle’s original specification.
Compare it with the current car and check whether:
the important features are present;
the seats and interior match;
the headlights are correct;
the multimedia system is original;
the steering wheel and body components match the version;
valuable components are not missing;
the advertisement does not promise features that are not present.
Differences may appear if certain components were replaced after an accident, installed later, or removed.
Some equipment added after production may work correctly, but it should not be presented as factory-installed equipment.
Analyse the mileage chronologically
Do not stop at the general conclusion displayed in the section. Read every mileage entry in chronological order.
For each record, check:
the date;
the mileage;
the country;
the source;
the difference from the previous reading;
the time between records.
A normal progression should increase over time.
Pay attention to:
readings lower than previous ones;
sudden decreases;
long periods without records;
unusually low mileage after years of intensive use;
differences between the mileage and the car’s condition.
A discrepancy does not automatically prove odometer manipulation. It may result from a data entry error or replacement of the instrument cluster.
Ask for documents and explanations regarding any significant difference.
The absence of mileage readings does not mean that the mileage is false
If the report contains only a few readings or identifies no records for a certain period, the correct conclusion is that no data was found in the available sources.
It does not automatically mean that:
the mileage was altered;
the car was not driven;
the report is incomplete;
the seller is hiding information.
Complete the check using invoices, roadworthiness inspections, service history, and electronic diagnostics.
Interpret the service history
Service records may include:
the date of the visit;
the mileage;
the work performed;
service operation codes;
inspected components;
replaced parts;
repairs completed under warranty.
Do not assume that the number of records represents every workshop visit.
The car may also have been maintained at independent workshops that do not transmit data to external sources. The owner may have invoices and documents that supplement the digital history.
Compare the work with the maintenance intervals and check whether important operations were completed, such as:
timing belt or timing chain maintenance;
transmission fluid replacement;
brake fluid replacement;
spark plug replacement;
filter replacement;
cooling system maintenance;
brake maintenance;
battery replacement.
If no evidence is available, include preventive maintenance in your post-purchase budget.
Analyse each damage event in context
For every recorded damage event, check:
the date;
the country;
the mileage;
the estimated value;
the estimated value range;
the affected areas;
the available photographs;
other events recorded around the same date.
The financial value alone does not indicate the severity of the accident.
An expensive repair may involve headlights, cameras, sensors, and exterior parts without affecting the structure. At the same time, a low value may represent only the initial estimate and may not include all the problems discovered later.
The affected areas and the quality of the repair are more important than the amount viewed on its own.
Multiple records do not automatically mean multiple accidents
The same event may generate several records:
the initial inspection;
an updated repair estimate;
the insurer’s assessment;
an auction listing;
photographs taken at different times;
a change to the estimated value.
Compare the date, country, mileage, and affected area before concluding that the car was involved in multiple accidents.
If the records are close together and describe the same area, they may belong to the same event.
Examine previous photographs
Photographs may provide more context than the description or estimated value of the damage.
Look for:
the direction of the impact;
missing components;
deformation of the engine compartment;
the position of the wheels;
the frame rails;
the pillars;
the side sills;
the roof;
the floor;
the airbags;
the interior;
signs of water or fire damage.
Compare the images with the car’s current condition. Check whether the affected components were replaced and whether there are signs that the repair was only cosmetic.
Photographs cannot confirm the quality of the current repair. A physical inspection is required.
What does the absence of damage records mean?
It means that no damage events were identified in the available sources for the VIN checked.
It does not guarantee that the car:
has never been damaged;
has no repainted panels;
has never been repaired;
retains all its original components;
has never had its airbags deployed.
Some accidents are repaired without an insurance claim or at a workshop that does not provide information to accessible databases.
Complete the report with paint thickness measurements, electronic diagnostics, and an inspection on a lift.
Check for commercial use
The report may indicate whether the vehicle was registered or used as:
a taxi;
a rental car;
a fleet vehicle;
a leased vehicle;
a passenger transport vehicle;
another type of commercial vehicle.
This information does not automatically mean that the car is in poor condition.
A fleet car may have been serviced regularly and driven mainly on motorways. However, a taxi or rental vehicle may have more significant urban and interior wear.
Compare the type of use with the mileage, service history, and current condition.
Check the theft records
The theft section shows the results of checks performed against the available databases.
If an active record or significant discrepancy appears:
do not pay for the car;
do not proceed with the transaction;
check the documents;
request official clarification;
contact the relevant authorities.
The absence of a record is not a universal guarantee because database availability differs between countries.
Check the recalls
A recall campaign is initiated when the manufacturer identifies a problem that must be corrected.
Check:
the description of the problem;
the affected system;
the stated risk;
whether the work has been completed;
what needs to be done next.
The existence of a recall does not automatically mean that the car is a poor choice. Many recall repairs are completed free of charge through the manufacturer’s authorised network.
Contact an authorised dealer to confirm the status and arrange the required repair.
How should you interpret emissions information?
Emissions data and the applicable emissions standard may affect:
taxes;
access to certain areas;
registration costs;
resale value;
eligibility for certain programmes;
use in other countries.
Compare the information in the report with the vehicle’s documents.
If you intend to register the car in another country, check the local regulations before buying.
What do the Euro NCAP results show?
Euro NCAP information provides context about the safety performance of the model tested.
Bear in mind that:
the results apply to a specific version and testing period;
testing protocols change over time;
two results from different years are not always directly comparable;
safety equipment may vary between versions;
the model’s result does not confirm the condition of the specific car being checked.
A car with a good rating may still be unsafe if its structure or airbags were repaired incorrectly.
Use the market valuation as a reference
The estimated market value helps you compare the asking price with similar vehicles.
Analyse:
the estimated range;
the year;
the mileage;
the engine;
the equipment;
the history;
the technical condition;
the market in which the car is being sold.
A price below the estimate does not automatically represent an opportunity. It may reflect damage, wear, incomplete documents, or required repairs.
A price above average may be justified by the equipment, maintenance, and condition, but it should be supported by evidence.
Check the ITP and legal information
The report may include information about the validity of the ITP roadworthiness inspection and other available administrative data.
A valid ITP does not guarantee:
the absence of damage;
genuine mileage;
perfect condition;
the operation of every system;
the quality of previous repairs.
Check the original documents, the seller’s identity, ownership rights, and any outstanding financing or encumbrances separately.
What does a section without records mean?
A section without results means that no data was identified in the sources consulted.
It does not automatically mean that:
the event never occurred;
the car has no problems;
the check was not performed;
the information was concealed.
Data availability varies depending on the country, make, age, and how the vehicle was used.
The report reflects the information available when it was generated.
How do you make the final decision?
After analysing the report, divide your findings into three categories.
Consistent information
The data matches the advertisement, the documents, and the condition of the car.
Points that require clarification
There may be periods without data, isolated readings, repainted panels, or minor differences that require an explanation.
Significant risks
These may include:
decreasing mileage readings;
structural damage;
deployed airbags;
photographs showing serious damage;
concealed commercial use;
a mismatched VIN;
a theft record;
inconsistent documents;
refusal of an independent inspection.
Do not decide based only on the number of warnings. Consider their severity and how they relate to one another.
The report does not replace a physical inspection
Before buying:
compare the VIN with the documents;
measure the paint thickness;
perform an electronic diagnostic scan;
inspect the car on a lift;
test every function;
complete a test drive;
request the invoices;
check the documents;
obtain written confirmation of the important information.
The report helps you understand where to look and which questions to ask.
Check the history before viewing the car
Enter the VIN on Certcar and analyse every section of the report, not only the damage or mileage.
Compare the information, request explanations for discrepancies, and complete the process with an inspection at an independent workshop before paying for the car.
Frequently asked questions
Does a report without alerts mean the car is perfect?
No. It means that no problems were identified in the available sources. The physical condition must be checked separately.
Does damage in the report mean I should give up on the car?
Not automatically. The severity, affected areas, photos and quality of the repair matter.
Why do multiple values appear for the same damage?
The same event can be evaluated in multiple stages or recorded by different sources.
Does a lack of service history mean the car has not been maintained?
No. Maintenance can be carried out in a workshop that does not transmit data or can only be documented by invoices.
Can I find out the actual mileage from the report?
You can analyse the recorded values and identify discrepancies. No source can confirm every kilometre travelled between two entries.
Does the Certcar report also check features?
Yes. The list of factory fitted features can be compared with the current equipment and the information in the advertisement.
