What a car history report tells you
A car history report pulls together records from insurance companies, police reports, auctions, and registration databases to show you what has happened to a specific vehicle. The report is tied to the car's Vehicle Identification Number (VIN)—a 17-character code unique to that car—so it follows the actual vehicle, not the owner.
The report will show you whether the car has been in accidents, had major repairs, been declared a total loss by an insurer, spent time in a flood or fire, been stolen, or had its odometer rolled back. It also lists how many owners the car has had, where it was registered, and whether there are any open recalls. This matters because a car with hidden damage history can fail unexpectedly, cost thousands to repair, or be unsafe to drive.
The most widely used reports come from Carfax and AutoCheck. Both pull from the same basic sources, but they weight the data differently and sometimes catch different records. Many dealerships provide a Carfax report for free; if you are buying from a private seller, you will usually pay for the report yourself.
Key Takeaways
- A car history report shows accidents, insurance claims, title problems, flood damage, and odometer fraud tied to a specific VIN.
- Carfax and AutoCheck are the two main report providers, and both charge per report unless a dealership provides one free.
- A clean report does not may provide the car has never been damaged—some accidents go unreported, especially minor ones paid in cash.
- Always get a pre-purchase inspection from a mechanic in addition to a history report, because the report only shows what was reported to insurance or the DMV.
How to order a Carfax report
Go to carfax.com and enter the VIN in the search box on the home page. You will see a preview of what the report contains—title history, accident history, service records, and ownership count. The full report costs around $25 to $30 for a single report, though prices vary by region. If you buy a package of multiple reports, the per-report cost drops.
Carfax also offers a subscription option where you can run unlimited reports for a set monthly fee, which makes sense if you are shopping for multiple cars. Once you purchase, you can view the report when ready online and read or print it. The report is yours to keep and share with a mechanic or lender.
Many dealerships have Carfax accounts and will print a report for you at no charge. If you are buying from a dealer, ask whether they have already run a report on the vehicle—if they have, they are usually required to show it to you.
How to order an AutoCheck report
AutoCheck is owned by Experian and works similarly to Carfax. Go to autocheck.com, enter the VIN, and you will see a preview. A single report costs around $25, and multi-report packages are available. AutoCheck pulls from different sources than Carfax—it has strong data from auctions and salvage yards—so it sometimes flags problems Carfax misses, and vice versa.
Some used-car dealerships, particularly those that buy at auction, use AutoCheck as their primary report. If you are buying from that type of dealer, ask whether they can run a report for you. You can also purchase directly from AutoCheck's website and read the report when ready.
Because Carfax and AutoCheck do not always report the same incidents, running both reports on a car you are seriously considering is worth the extra cost. A discrepancy between the two can point to something worth investigating further with a mechanic.
What to look for in a history report
Start with the title section. Look for a clean title—meaning the car has not been declared a total loss, salvage, flood-damaged, or branded as a lemon. A salvage title means an insurer paid out a total loss claim on the car. A rebuilt title means the car was salvaged and then repaired and re-registered. Both are red flags because the repair quality is unknown and resale value is permanently lower.
Next, check the accident and damage history. The report will list reported accidents, the severity (minor, moderate, severe), and whether the car was declared a total loss. Pay attention to the number of owners and how long each owned the car. A car that changed hands five times in three years suggests problems. A car owned by the same person for eight years suggests stability.
Look at the service records section if the report includes it. Regular oil changes and maintenance suggest the owner cared for the car. Long gaps between services or no records at all mean you cannot verify the car was maintained. Check whether there are any open recalls listed—if there are, the seller is responsible for having them fixed before you take ownership, or you can negotiate a discount to cover the cost yourself.
Why a history report is not enough
A clean history report does not mean the car is in good condition. Many accidents, especially minor ones, are never reported to insurance if the owner paid for repairs out of pocket. A car can have frame damage, transmission problems, or engine wear that never triggered an insurance claim. The report only shows what was reported to insurers, police, or the DMV—not what actually happened to the car.
This is why a pre-purchase inspection by a mechanic is essential. A mechanic can put the car on a lift, check the frame for welding or damage, run a compression test on the engine, test the transmission, and look for signs of past repairs. They can spot hidden problems that a history report will never catch. Budget $100 to $200 for a thorough inspection—it is the cheapest insurance you can buy before spending thousands on a used car.
Odometer fraud and mileage checks
Both Carfax and AutoCheck flag inconsistencies in reported mileage. If a car was registered with 80,000 miles one year and 60,000 miles the next, the report will note the discrepancy. This is a sign of odometer rollback—illegal tampering to make the car appear to have lower mileage than it actually does.
Odometer fraud matters because mileage determines wear on the engine, transmission, and suspension. A car with 200,000 actual miles but showing 100,000 on the odometer will fail much sooner than a car that genuinely has 100,000 miles. The history report catches some cases, but not all. If mileage seems too low for the car's age, or if there are gaps in the service records, ask a mechanic to inspect the engine and transmission for signs of high mileage wear.
Flood and fire damage
Both Carfax and AutoCheck pull data from insurance claims and salvage auctions to identify cars that have been flooded or damaged by fire. A flooded car is particularly dangerous because water can corrode electrical systems, cause the engine to seize, and create mold inside the cabin. These problems can take months to appear, making a flooded car a financial trap.
If a report shows flood or fire damage, the car will usually have a branded title (salvage or rebuilt). However, some flood damage goes unreported, especially if the owner had the car dried out and repaired without filing an insurance claim. Signs of past flooding include a musty smell inside the car, rust on bolts and fasteners under the hood, water stains on the interior trim, and corrosion on electrical connectors. A mechanic can spot these during an inspection.
Frequently Asked Questions
Can I check a car's history for free?
Some dealerships provide free Carfax reports, and you can see a preview of both Carfax and AutoCheck reports for free before you pay. However, the full detailed report from either service costs money—typically $25 to $30 per report. There is no legitimate free alternative that pulls from the same insurance and registration databases.
What if the history report shows an accident but the car looks fine?
An accident report does not tell you how well the car was repaired. A minor fender-bender fixed properly is different from a major collision repaired with cheap parts and poor alignment. Have a mechanic inspect the car, paying special attention to the damaged area. They can check whether the repair was done correctly and whether there is hidden damage underneath.
Should I buy a car with a salvage title?
A salvage title means the car was declared a total loss by an insurer. It can be rebuilt and driven legally, but the title will always be branded, which makes it harder to sell later and lowers the value permanently. Insurance companies often charge more to insure a salvage-title car. Unless the price is significantly lower and you have had a thorough inspection, it is usually safer to buy a car with a clean title.
What does a rebuilt title mean?
A rebuilt title means the car was salvaged (declared a total loss) and then repaired and re-registered. The car is legal to drive and insure, but the title is branded forever. The quality of the rebuild is unknown—some shops do excellent work, others cut corners. Always have a mechanic inspect a rebuilt-title car thoroughly before buying.
Do I need both a Carfax and AutoCheck report?
For a car you are seriously considering buying, running both reports is worth the extra $25 to $30. They pull from different sources and sometimes catch different incidents. If one report shows something the other does not, it is worth investigating with a mechanic. If both reports are clean, you have more confidence in the car's history.
