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.

Frequently asked questions

What is an AutoCheck report?

AutoCheck is a vehicle history report from Experian. It covers title history, reported accidents, odometer readings, owner count and registration events — and is particularly strong on auction data, the canonical source for damage and salvage events. It also gives each vehicle an AutoCheck Score for at-a-glance comparison.

Is AutoCheck as good as Carfax?

They overlap heavily but differ at the edges: Carfax generally has the broader service-history database, while AutoCheck is stronger on auction-flagged damage and cheaper in multi-report packs. For a single high-stakes purchase, running both is the safest play — each can catch what the other misses.

Is AutoCheck reliable?

Yes — it is run by Experian and pulls from the same official sources as other history providers (state title records, insurance, auctions). But no history report sees unreported damage. Treat any report as the official story, and pair it with an independent pre-purchase inspection for the truth about the actual car.

Which is cheaper, Carfax or AutoCheck?

AutoCheck is typically cheaper per report, and its multi-report packs are popular with private buyers comparing several cars. Carfax single reports cost more, but dealers often provide them free with a listing.

Do I need a vehicle history report for a private-party sale?

Strongly recommended. Get the VIN from the seller before you travel, run at least one report, and walk away from any seller who will not share the VIN. The report cost is trivial against the price of a car with hidden damage.
