Start With the Vehicle History Report — But Do Not Stop There

A Carfax or AutoCheck report is the obvious first step, and it is worth running every time. These reports pull from insurance claims, police reports, and title records to flag accidents, total loss declarations, and odometer discrepancies. They are useful, but they are not complete. An accident that was never reported to insurance, whether it involved a cash repair, a private settlement, or damage that was simply ignored, will not appear on a vehicle history report. The report is a starting point, not a finish line.

Look at the Paint Under Different Lighting Conditions

Repainted panels are one of the most reliable indicators of past accident repair, and they are often visible if you know what to look for. Take the vehicle outside in daylight and look along each panel at a low angle. Repainted areas often show a slightly different texture, sheen, or color tone compared to factory paint. Look for overspray on rubber trim, door jambs, and plastic moldings near any panel that appears freshly painted. Orange peel texture that is noticeably different between panels is another common sign.

Check Panel Gaps and Alignment

Factory-assembled vehicles have consistent, even gaps between panels. Open and close every door, the hood, and the trunk. Look at the gap between the fender and the door, the door and the B-pillar, and the hood and the front fenders. Uneven gaps, panels that do not sit flush, or doors that require extra effort to close properly are all signs that the vehicle’s structure or body panels have been disturbed and repaired, sometimes not perfectly.

Look for Mismatched Hardware and Fasteners

When body panels are replaced after an accident, the bolts and fasteners that hold them in place are sometimes stripped, cross-threaded, or replaced with non-matching hardware. Pop the hood and look at the bolts holding the front fenders in place. Check the bolt heads in the door hinges. Signs of tool marks on fasteners, mismatched bolt heads, or rust around fastener holes on an otherwise clean vehicle all point to prior work.

Inspect the Undercarriage and Frame Rails

Get under the vehicle if you can, or have it put on a lift at a shop. Look at the frame rails that run along the underside of the vehicle from front to rear. Welds that look rough, areas where metal has been straightened or has ripple marks, and mismatched undercoating all suggest structural repair. A clean, untouched undercarriage looks consistent from front to back.

Have It Inspected by a Professional Before You Buy

The single most reliable way to know what you are buying is to have a professional collision repair technician inspect the vehicle before purchase. At CDM Collision Center, we offer pre-purchase inspections that go beyond what a general mechanic will check. We know exactly where to look for signs of prior accident repair, and we can tell you what we find in plain language so you can make an informed decision.

If the seller will not allow a pre-purchase inspection at a shop of your choosing, that is itself a significant red flag. Book your pre-purchase inspection today.
