CARFAX only shows rust when someone recorded it, like a repair, a corrosion recall, or years in salt-belt states. How to read those clues, tell salt rust from flood rust, and judge what a lift inspection finds.
CARFAX shows when a car was auctioned or sold to a new owner, but not what anyone paid. What the sale lines mean, what History-Based Value is, where real prices get recorded, and how to negotiate without the old number.
CARFAX shows registration history, the dated issued or renewed lines and states it uses to estimate owners, but not whether tags are current or suspended. How to read moves and gaps, spot a cloned VIN, and check status with the DMV.
CARFAX shows the damage an insurer, police, or shop reported, plus total losses and title brands, but it is not a claims database. Which claims slip through, how NMVTIS and NICB VINCheck fill gaps, and why the seller's C.L.U.E. report matters.
A deer hit lands on CARFAX only when an insurer, police report, or body shop sends the record in, so cash-paid repairs can vanish. How animal strikes get reported, why fall matters, and what to check before you buy.
CARFAX tracks the VIN, so speeding, parking, camera, and toll tickets don't print on the report. Where tickets really go, how unpaid ones block a registration or get a car towed, and what to check before you buy.
CARFAX and AutoCheck only list accidents a police department, insurer, shop, dealer, or auction reported. Why cash-paid crash repairs slip through, how long reports lag, and how to find a hidden repair before you buy.
CARFAX and AutoCheck have no smoker field, so a smoked-in car can carry a clean report. How to spot smoke yourself, what thirdhand smoke research says, what removal and resale really cost, and what a report still catches.
CARFAX lists oil changes only when a reporting shop or dealer sends the record in. How to read gaps against the owner's manual schedule, use oil rows as an odometer check, and why missing records can hurt warranty claims.
CARFAX lists reported service visits, recalls, accidents, and title brands, but it does not diagnose how a car runs. Which clues to read, how to spot a cleared check-engine light, and what a mechanic finds instead.
