Vehicle history reports miss 1-in-6 accidents, leaving used car buyers blind

Used car buyers rely on Carfax and AutoCheck reports as their primary defense against purchasing damaged vehicles, but these reports only capture incidents reported to insurance companies and state DMVs. So what? 1 in 6 used vehicles has been in an accident not listed on any vehicle history report. Cash repairs, independent shop work, out-of-state incidents, and minor collisions routinely go unreported. So what? A buyer pays $25,000 for a 'clean history' used car that actually had $8,000 in frame damage repaired at a body shop that never reported it. So what? The hidden frame repair causes accelerated tire wear, alignment drift, and compromised crash protection — the crumple zones have already crumpled once. So what? The buyer discovers this months later when a mechanic notices the damage during unrelated service, by which time they've lost thousands in depreciation and have no recourse against the seller. So what? 450,000+ vehicles with rolled-back odometers are sold annually, compounding the trust gap. This persists because there is no mandatory universal reporting system — body shops, independent mechanics, and private sellers have no obligation to report repairs to any central database.
