Carfax Reports: What They Are and Why Sellers Sometimes Hide Them

A Carfax Vehicle History Report compiles data from 100,000+ sources (DMVs, police, repair shops, auctions, insurers) into a timeline of a car's life.

What It Shows

• Title brands: salvage, flood, lemon, rebuilt, junk
• Accident/damage reports (severity, airbag deployment)
• Ownership count & type (personal, rental, fleet, lease)
• Service records (dealer maintenance, oil changes, recalls)
• Odometer readings (rollback detection)
• Registration locations (geographic history)
• Recall status

Why Sellers Might Withhold It

1. Concealing damage: Unreported accidents, flood damage, frame repairs.
2. Title washing: Moving a branded title through lax states to clean it.
3. Odometer fraud: Rollback before sale.
4. Ignorance: Private sellers may not know Carfax exists or matters.
5. Cost: $44.99 single; dealers get bulk discounts.

Buyer's Checklist

• Always request the report. Refusal = red flag.
• Cross-check with NMVTIS (gov't database, cheaper).
• Get a pre-purchase inspection (PPI) by independent mechanic—Carfax misses unrepaired/unreported issues.
• Verify VIN on dashboard, door jamb, engine, title.

Carfax isn't perfect (gaps in reporting), but it's the best first filter. A clean report doesn't guarantee a clean car; a dirty report guarantees you need to dig deeper.
