How to tell if a used car has been in an accident
Use three checks together. Look for repaint signs: mismatched color or texture, overspray on rubber seals and trim, uneven panel gaps and doors that don't close squarely. Run a history report, which shows accidents that were reported to its sources. And get a mechanic to look underneath on a lift for welds, kinked parts and fresh undercoating. Consumer Reports found history reports can miss damage, so no single check is enough.
Signs you can see yourself
| Where to look | What suggests repair |
|---|---|
| Paint, along each side at an angle | A panel slightly different in color, gloss or texture |
| Rubber seals, trim, door jambs, under the hood | Paint overspray, or a rough texture you can feel |
| Gaps between panels | Gaps wider on one side, or panels that don't line up |
| Doors, hood, trunk | Hard to close, or not sitting square |
| Bumper covers | Repainted or replaced covers with a slightly different finish |
| Steel panels (magnet) | A magnet that won't stick may mean body filler |
| Bolts on fenders and hood hinges | Scratched or turned bolt heads where panels were removed |
| Tires | Uneven wear, which can follow misalignment after a hit |
Consumer Reports' list of rebuilt-wreck warning signs adds a few more: an airbag warning light that never lights up at start-up, seat belts with damaged or melted fibers, and parts stickers (such as CAPA labels) on body panels, which can indicate aftermarket collision parts.
What a history report shows, and misses
A vehicle history report gathers records from sources like insurers, police reports, auctions, title agencies and repair shops. If an accident was reported to one of those sources, it can show up, sometimes with an estimate of severity or the area of damage.
But reports only know what was reported. In a 2009 investigation, Consumer Reports found damaged cars that got "clean" reports, in some cases from all five services it tested. An accident paid for in cash, or never reported to police or an insurer, can leave no record at all. The FTC also notes that a history report is not a substitute for an independent inspection.
A good order is: a free check first (NICB's VINCheck for insurance total losses and theft in the US), then a paid history report on the car you're serious about, then an inspection.
Check the VIN on the car you're looking at
See where it was built and its model year, then check its title history for salvage, flood, odometer and theft records.
What only a mechanic can see
Consumer Reports suggests having the car put on a lift and looking for:
- Welds on frame rails or around the hood apron that don't look like factory welds
- Kinked or bent structural parts, or dents in the floor pan
- Fresh undercoating in one area, which can cover recent repairs
- Marks on the strut towers that suggest the frame was pulled straight
Some inspectors also use a paint thickness gauge, which can show which panels were refinished.
Does a past accident mean don't buy?
Not always. A properly repaired minor accident can be fine, and it should lower the price. What matters is the severity, whether structural parts or airbags were involved, and the quality of the repair. Ask for the repair invoice. Structural damage, deployed airbags or a salvage or rebuilt title deserve much more caution, and a lower price.
Questions
Can a car have a clean Carfax and still have been in an accident?
Yes. Reports only include accidents that reached their data sources. Consumer Reports found damaged cars with clean reports, so always add a physical inspection.
What is the easiest sign of accident repair to spot?
Paint that doesn't quite match from panel to panel, and overspray on rubber seals or trim. Check in daylight, at an angle.
Is a repaired accident car worth buying?
It can be, at the right price, if the damage was minor and well repaired. Get the repair invoice and a mechanic's inspection, and be very cautious with structural damage or deployed airbags.
