Carfax vs AutoCheck: Which Vehicle History Report Should You Use?

Whether you are buying privately or from a dealer, a vehicle history report is the single cheapest piece of due diligence you can do. The two big players in the United States are Carfax and AutoCheck. They overlap a lot but they are not identical. Here is what you actually need to know.

What both cover

• Title history — clean, salvage, rebuilt, branded.
• Reported accidents and damage.
• Odometer readings over time (flags rollback).
• Number of previous owners.
• Service and registration events.
• Lien and recall information where available.

Where they differ

Carfax

• Generally the broader service-history database — pulls from a huge network of dealers and independent shops.
• Better at showing the maintenance trail.
• Single-report pricing is higher than AutoCheck; bulk plans are aimed at dealers.
• Free if a dealer subscribes, which is common.

AutoCheck

• Owned by Experian; stronger on auction data, which is the canonical source for damage and salvage events.
• AutoCheck Score — a single number summarising vehicle history, useful for comparing two cars at a glance.
• Bulk pricing is more accessible; 25-report packs are popular with private buyers shopping around.
• Sometimes catches auction-flagged damage that Carfax misses.

Which one to use

• If a Carfax is offered for free by a dealer or the seller, take it — read it carefully.
• If you are comparing several cars on the private market, an AutoCheck multi-report pack is usually the better value.
• For maximum confidence on a single high-stakes purchase, run both — the cost is small relative to the price of a car, and each can catch what the other misses.

What history reports do NOT replace

Neither report sees:

• Unreported accident damage repaired privately.
• Mechanical condition right now (the report cannot drive the car).
• Flood or fire damage that was never reported to insurance.
• Cosmetic or interior condition.

The report tells you the official story; the pre-purchase inspection tells you the truth about the car in front of you. Both are essential.

The full due-diligence routine

1. Get the VIN from the seller before driving anywhere.
2. Run Carfax or AutoCheck (or both for big-ticket buys).
3. Inspect in person in good light.
4. Take it for a 20-minute test drive.
5. Pay for an independent pre-purchase inspection.
6. Verify title and lien status before paying.
