Carfax Red Flags
If any of these ten things appears on a Carfax, slow down. Some are deal-killers; others are negotiation leverage.
Ten things that should slow you down on a Carfax. The first three are near-automatic walks.
1. Salvage, flood, or rebuilt
Even a cosmetically rebuilt car has limited resale, trouble getting financing, and may be uninsurable at full value. Only worth it if the discount is massive and you plan to keep the car forever.
2. Odometer rollback
If any reading is lower than a prior reading, walk. Rollback is fraud. If the seller tampered with that, assume other things.
3. Owner turnover
Four or more owners on a car under ten years is a flag. Each short ownership is someone who regretted the purchase enough to flip the car.
4. Undisclosed rental or fleet
Rental cars get driven hard by non-owners. Carfax discloses rental use. If the listing didn't mention it, the seller knew and didn't tell you.
5. Structural damage
"Structural damage" means the frame took a hit. Rebuilt frames are rarely as rigid as original.
6. Multiple accidents
Two is borderline. Three or more is a pattern.
7. Open recalls
Not a dealbreaker. Dealers fix recalls free. Just factor the trip into your plan.
8. State hopping after an accident
Totaled in Florida, retitled in Texas, retitled in Georgia without a flood brand. Carfax catches this because it pulls from every state.
9. Service gaps
Dense dealer service for years one through four, then nothing on a ten-year-old car. Usually means the car was parked or the owner stopped maintaining it.
10. Lemon law buyback
Manufacturer bought it back for recurring unfixable problems. The problems don't vanish on resale. Walk.
Run a cheap Carfax report before you make an offer. Catching any of the top three saves you orders of magnitude more than the report costs.
