What an AutoCheck report is
AutoCheck is Experian Automotive's vehicle history report. Like CARFAX, it is keyed to the VIN and pulls from state DMV title records, insurance and salvage databases, police-reported accidents, odometer filings, and fleet and rental operators. You get ownership timeline, title brands, reported damage, mileage history, and use type — the same core skeleton any serious buyer needs.
Two things make it distinct: its auction coverage, and the AutoCheck Score. Both are reasons to run it alongside a CARFAX rather than instead of one.
The auction data advantage
Millions of used vehicles a year pass through wholesale auto auctions — off-lease returns, rental retirements, fleet cycles, trade-ins a dealer chose not to retail, and insurance salvage units. At the auction, the seller must announce known conditions: frame damage, prior salvage, true-mileage-unknown, flood, and so on. Those announcements and sale records are Experian's home turf.
Practically, that means a car that was announced as structurally damaged at auction in one state and then quietly retailed in another can surface on an AutoCheck even when the retail-side paper trail looks clean. If the car you are looking at was acquired at auction — which is true of an enormous share of independent-dealer inventory — AutoCheck is not optional. It is the report most likely to catch the problem.
- Auction sale dates and locations, showing how many times the car has been wholesaled.
- Announced conditions declared by the selling dealer at the block.
- Rapid resale patterns — a car auctioned three times in eighteen months is a car other dealers kept rejecting.
- Cross-state title movement that can indicate title washing.
How to read the AutoCheck Score
The AutoCheck Score is a 1–100 rating comparing the vehicle to similar vehicles of the same year, make, and model. Alongside it, the report shows the typical score range for that peer group — for example "Score 88, similar vehicles 82–91."
- Inside or above the range: history is normal for this kind of car at this age and mileage.
- Slightly below the range: usually explained by higher owner count, commercial use, or a minor reported incident. Ask what drove it down.
- Well below the range: something material — a brand, a serious accident, an odometer problem, or heavy fleet use. Treat it as a stop sign until explained in writing.
- A high score is not a guarantee. It is a relative rating built only from reported data, so it inherits every gap in that data.
The score is most useful as a triage tool. When you are comparing five similar cars across town, it lets you rank them in seconds and spend your inspection budget on the two worth driving to.
Why it matters just as much as CARFAX
History providers do not share data with each other. Each signs its own agreements with repair shops, auctions, insurers, and agencies. An event reported to one is not automatically on the other. That is the entire argument in one sentence: a clean CARFAX proves nothing was reported to CARFAX.
| CARFAX | AutoCheck | |
|---|---|---|
| Strongest data | Service & maintenance records, detailed accident narratives | Wholesale auction records, title brands, use history |
| Summary metric | Pass/fail style badges | AutoCheck Score, 1–100, vs similar vehicles |
| Owned by | CARFAX (IHS Markit / S&P Global) | Experian Automotive |
| Typical cost | ~$45 single report | ~$25 single, ~$50 multi-report package |
| Best for | One- or two-owner retail cars with dealer service history | Off-lease, fleet, rental, and auction-sourced cars |
How to read the report, section by section
- Score and score range — read them together. The range is the context that makes the number mean anything.
- Title brand check — AutoCheck runs the VIN against all 50 states and flags salvage, junk, rebuilt, flood, fire, hail, lemon buyback, and odometer discrepancies.
- Ownership timeline — count owners and note how long each held the car. Short holds stacked together are a warning.
- Use history — personal, lease, rental, fleet, taxi, government, or commercial. A rental past is not disqualifying, but it should be priced in.
- Auction and sale records — the section CARFAX often lacks. Every appearance at the block is a data point about how the trade valued this car.
- Odometer readings — the sequence must always increase at a believable rate. Any decrease or 'not actual mileage' entry ends the conversation.
Red flags on an AutoCheck
- A score far below the similar-vehicle range with no explanation the seller can document.
- Any title brand at all on a car priced as clean-title retail.
- Multiple auction runs in a short window — the wholesale market repeatedly passed on this car.
- Announced frame or structural damage at auction, regardless of how the retail listing describes the car.
- A title issued in a flood-affected state followed quickly by a title in a distant state.
- Reported mileage that stalls for years then resumes — the car likely sat inoperable or was in long-term repair.
Why smart buyers run both
Roughly $50 buys you both reports. Set against a $20,000 purchase, a $4,000 hit to resale value from an undisclosed brand, or a $3,000 structural repair, that is not a real expense — it is the cheapest line item in the entire transaction.
The workflow we recommend to every buyer is simple: get the VIN → run AutoCheck and CARFAX → compare them for discrepancies → pay for a pre-purchase inspection by your own mechanic. Discrepancies between the two reports are themselves information. If one shows an auction announcement of damage and the other shows nothing, you now know precisely what to ask the seller, and precisely what to have the inspector look at.
Neither report measures mechanical condition. Neither can see a collision repaired with cash and never claimed. They tell you the car's documented past; the inspection tells you its present. Do all three and you have removed nearly every avoidable risk in a used-car purchase.
Frequently asked questions
What is an AutoCheck report?
AutoCheck is a vehicle history report from Experian Automotive. Like CARFAX it is tied to a car's 17-character VIN, and it compiles DMV title records, title brands, odometer readings, accident and damage reports, and use history. Its distinguishing strength is auto-auction data: Experian has records from the major wholesale auctions that move millions of used cars a year, so cars that passed through the wholesale channel are often documented more completely on AutoCheck.
What is the AutoCheck Score?
The AutoCheck Score is a number from 1 to 100 that rates a vehicle against similar vehicles of the same year, make, and model. The report also shows the typical score range for that comparison group. A car scoring inside or above its range has a history in line with its peers; a score well below the range means something in its history — accidents, brands, many owners, heavy commercial use — puts it behind comparable cars.
Is AutoCheck better than CARFAX?
Neither is strictly better; they weight different data. CARFAX generally has deeper service and maintenance records and more detailed accident narratives. AutoCheck generally has broader auction records, strong title-brand coverage across all 50 states, and the comparative score. For a one- or two-owner retail car, CARFAX alone is usually enough. For an off-lease, fleet, rental, or dealer-auction car, AutoCheck frequently surfaces events CARFAX does not list.
Should I run both AutoCheck and CARFAX?
On any car you are seriously considering, yes. Together they cost roughly $50 — a fraction of one repair bill on an undisclosed accident car. Because each provider signs its own data agreements, an event reported to one is not guaranteed to appear on the other. Running both is the only reliable way to close the gaps.
Does AutoCheck show flood and salvage titles?
Yes. AutoCheck reports title brands including salvage, junk, rebuilt, flood or water damage, fire damage, hail, lemon-law buyback, and odometer discrepancies, sourced from state DMV records. Because it also carries auction announcements, it can catch a branded or announced-damage car that was later retitled in a different state.
How much does AutoCheck cost?
Experian sells single AutoCheck reports for roughly $25, with a multi-report package for about $50 that covers unlimited lookups for a set period — useful if you are comparing several cars at once. Many dealers, including approved dealers on VendacarUSA, provide a report at no cost when you ask.
Every vehicle on the VendacarUSA marketplace is listed by a vetted, approved dealer with VIN-verified details — so you can run both history reports before you spend a Saturday driving to a lot.
