  • Largest service-record database, built on long-standing dealer partnerships
  • The most recognized brand in vehicle history reports
  • Buyback Guarantee program on qualifying vehicles
  • Dedicated mobile app on iOS and Android

Cons

  • The most expensive of the major reports, so checking several cars adds up fast
  • No auction photos or wholesale condition grades
  • Report layout can feel cluttered with upsell prompts and dealer listings
#2

AutoCheck Single reports plus cheaper discounted multi-report packs

Pros

  • Owned by Experian, with access to extensive automotive data
  • AutoCheck Score condenses a vehicle's history into one number for quick side-by-side comparison

Cons

#3

VinExposed $0.99 introductory access

Pros

  • Free VIN preview before you pay — see year/make/model and which record categories are available
  • Names its sources: NMVTIS title/odometer and salvage-rebuilt-flood-junk brands, NICB theft and total-loss, salvage-auction listings, and NHTSA recalls
  • Auction photos and condition grades sourced from major wholesale auctions
  • One plan includes up to 5 reports, viewable online and downloadable as PDF

Cons

  • Newer service with less brand recognition than Carfax or AutoCheck
  • No mobile app yet — reports are accessed through the web browser
  • No proprietary score like AutoCheck, and a smaller service-record database than Carfax

Our Verdict

Carfax and AutoCheck are both solid, well-established reports: Carfax leads on dealer-linked service records and brand recognition, while AutoCheck (owned by Experian) offers its numeric AutoCheck Score and cheaper multi-report packs for shoppers comparing many cars. Neither is cheap, and no single report contains every event, so an independent pre-purchase inspection still matters. If price is your main concern, VinExposed is worth a look as an affordable third option: a free VIN preview before you pay, $0.99 introductory access with up to 5 reports, named sources (NMVTIS, NICB, salvage auctions, NHTSA), and auction photos when available. Choose based on which records you need and how many vehicles you plan to check.

Frequently Asked Questions

What is the main difference between Carfax and AutoCheck?

Carfax emphasizes depth of service and repair records gathered from its large dealer network, which is useful for tracing how a car was maintained. AutoCheck, owned by Experian, leans on strong auction data and its proprietary AutoCheck Score, a single number meant for quick side-by-side comparisons. Both draw title and brand data from the federal NMVTIS system, but their added coverage and presentation differ.

Is Carfax or AutoCheck more accurate?

Neither is definitively more accurate — each report reflects the records available to it, and no database contains every event in a car's life. Carfax tends to have more dealer-linked service records, while AutoCheck often has broader auction history. Whichever you choose, treat the report as a screening tool and still get an independent pre-purchase inspection before buying.

Which is cheaper, Carfax or AutoCheck?

AutoCheck is generally the cheaper of the two, especially through its discounted multi-report packs, whereas Carfax is typically the most expensive of the major reports at around $44+ for a single lookup. If budget is the priority, VinExposed offers $0.99 introductory access with up to 5 reports and a free preview before you pay.

What is the AutoCheck Score?

The AutoCheck Score is a proprietary numeric rating, unique to AutoCheck, that summarizes a vehicle's history into a single number and a suggested range for similar vehicles. It's handy for quickly ranking several cars at once, but the underlying algorithm isn't fully transparent. If you'd rather see the raw records yourself, VinExposed presents the underlying title, odometer, recall, and auction data directly instead of an opaque score.

Is there a cheaper alternative to both Carfax and AutoCheck?

Yes. VinExposed is a lower-cost option that lets you preview a VIN free before checkout and then unlock reports for $0.99 introductory access, with up to 5 reports per plan. It aggregates NMVTIS title and odometer history, NICB theft and total-loss records, salvage-auction listings with photos, and NHTSA recalls, naming the contributing sources. Coverage isn't identical to Carfax's service-record depth, so for any car you're serious about, still schedule an independent inspection.
