Buying basics · 8 min read
A clean-looking used car can hide flood damage, odometer fraud, or a salvage title. History reports are your first line of defense — but they are not the whole defense. Here is the complete checklist.
Updated October 2026 · By the CARC research team
Carfax and AutoCheck pull from DMVs, insurers, and service shops: accidents, title brands (salvage, rebuilt, flood), odometer readings, service history, and number of owners.
What they miss: unreported accidents (no police report, no insurance claim), maintenance done at home, and anything in the gap before the car entered the reporting system. A clean report is necessary but not sufficient.
Salvage or rebuilt title; flood/water damage brand; odometer rollback or gaps; frame/structural damage reported; airbag deployment; more than 3 owners in 5 years; title issued in a different state than the seller (title washing); liens still on the title; VIN plates that look tampered with; seller refuses independent inspection.
Spend $150–$250 on a pre-purchase inspection at an independent mechanic — never the seller's shop. It catches what reports miss: worn suspension, hidden rust, failing transmissions.
Any seller who refuses an inspection is telling you everything you need to know. Walk away.
The VIN on the dashboard, driver's door jamb, and title must all match. Mismatches suggest major repairs, VIN swapping, or worse.
Run the VIN through the free NHTSA recall checker — open recalls are common on used cars and free to fix at any dealer.
