What a proper assessment finds
Impact damage rarely stops at the panel. A knock that looks like a bumper and a wing can have moved a crash structure, disturbed suspension geometry, or upset the sensors and cameras that modern driver-assistance systems depend on.
That last one matters more each year. Cars increasingly carry radar, cameras and parking sensors in exactly the places that get hit, and putting the bodywork back without addressing the systems behind it leaves the vehicle looking repaired without being repaired.
This is why the assessment is done by people who will also carry out the work. An estimate written to a number, then handed to someone else to deliver, is where corners start getting cut.
