AutoCheck vs Carfax (2026): Which Report Is Better for a Rebuilt Title Car, What the AutoCheck Score Means, and What Neither One Shows
November 12, 2026
Short answer: AutoCheck and Carfax are both vehicle history reports, and on a rebuilt title car either one will usually show you the brand. AutoCheck, made by Experian, adds the patented AutoCheck Score, a 1 to 100 rating you read against a range for similar cars, and it sells reports in a 5-pack. Carfax says it draws on more than 151,000 data sources and backs its reports with a Buyback Guarantee for missed DMV title brands. Neither one tells you how severe the original hit was or how big a discount the car should carry, which is the part a rebuilt title buyer cares about most.
Think of the two reports like two credit bureaus. They mostly agree, they occasionally catch different things, and smart borrowers look at more than one. A rebuilt car is the same: the history report tells you what happened, and you still need a second tool to tell you what it means for the price.
Key takeaways
- AutoCheck sells one report for $29.99 or 5 reports over 21 days for $59.99, as published on autocheck.com on November 12, 2026.
- The AutoCheck Score runs from 1 to 100. Read it next to the Score Range for similar cars, not on its own.
- Title brands "such as salvaged or rebuilt title" lower the AutoCheck Score, so a rebuilt car scoring below the range is expected.
- Carfax's Buyback Guarantee covers DMV-issued brands it missed, including Salvage, Rebuilt and Flood.
- For a rebuilt car, pair a history report with a ReVroom Report, which shows the severity grade, a severity graphic, an estimated savings percentage, and where and when the car was auctioned.
What is the difference between AutoCheck and Carfax?
Short answer: the data overlaps a lot. The big differences are the AutoCheck Score, the way each one prices multiple reports, and what each company promises if it misses something.

What is an AutoCheck score, and what is a good one?
Short answer: it's a 1 to 100 summary of the car's history, and a "good" score is one that lands inside or above the Score Range for similar cars. The number on its own only tells half the story.
AutoCheck describes the score as "a rating summarizing the longer list of report data." It's built from the car's age, class, mileage, number of owners, and events like accidents, theft or taxi use. AutoCheck's own example makes the point: a car scoring 84 can have a better history than one scoring 89, if the first car's range is 76 to 81 and the second car's range is 90 to 95. Same idea as a test score graded on a curve.
For a rebuilt title car, expect the score to sit below the range. AutoCheck lists "Title brands such as salvaged or rebuilt title" among the factors that pull the score down, along with frame and water history. That isn't a red flag on a rebuilt car. It's the brand doing what it's supposed to do. What you want to know next is how serious the original hit was, and that's a different question.
Which is better for a rebuilt title car, AutoCheck or Carfax?
Short answer: either one will usually show the brand. AutoCheck is the cheaper way to check several cars, and the score helps you compare them. Carfax is the one many sellers already have on hand, so ask for it before you buy your own.
If you're comparing three or four rebuilt cars, the AutoCheck 5-pack covers all of them for less than two single reports. If you've narrowed it to one car and the seller already has a Carfax, read that one and spend your money on an independent inspection instead. Our Carfax VIN lookup guide covers what Carfax shows and what you can check for free first.
What does neither AutoCheck nor Carfax tell you about a rebuilt car?
Short answer: how severe the original hit was, and whether the price reflects it.
A history report is a timeline. It can tell you the car was branded, when it changed hands and roughly what was reported. It wasn't built to grade a rebuilt car, so "rebuilt" looks about the same on a car that had a cracked bumper as on one that needed far more work. That's the gap a ReVroom Report fills. It shows four things: our in-house severity grade (minor, moderate or severe), a detailed severity graphic with highlights, an estimated savings percentage against comparable clean-title cars, and where and when the vehicle was auctioned. It isn't a vehicle history report and doesn't replace one. It answers the question a history report can't.
Repair photos, where available, live on ReVroom listing pages, not in the report. And if you want to skip straight to the light end, you can shop minor-severity rebuilt cars only.
Which should you run first on a rebuilt title car?
Short answer: the free checks first, then one history report, then a severity check on the car you're serious about.
- Free checks. Confirm the VIN on the car matches the title and run the free VIN checks covered in our Carfax VIN lookup guide.
- One history report. AutoCheck if you're comparing several cars, Carfax if the seller already has one.
- A ReVroom Report. The severity grade, the severity graphic, the estimated savings and the auction record, so you know whether the price makes sense.
- An independent inspection. A mechanic you choose, on the car itself.
I bought my own rebuilt car at 53 percent off. The reports didn't make that decision for me, but they made it a lot easier to say yes.
Frequently asked questions
Is AutoCheck or Carfax better?
They overlap a lot. AutoCheck adds the AutoCheck Score and sells 5 reports over 21 days for $59.99 (as published November 12, 2026), which helps when you're comparing several cars. Carfax says it draws on more than 151,000 data sources and offers a Buyback Guarantee for missed DMV title brands. On a rebuilt title car, either will usually show the brand.
What is an AutoCheck score?
A 1 to 100 rating that summarizes a car's history from AutoCheck, an Experian product. You read it against the Score Range for vehicles of similar age and class: a score inside or above the range means the history compares well with similar cars.
What is a good AutoCheck score?
One that sits inside or above the Score Range shown for similar vehicles. The number alone isn't enough, because ranges differ by age and class. On a rebuilt title car, a score below the range is expected, since title brands lower the score.
Does a rebuilt title lower the AutoCheck score?
Yes. AutoCheck lists title brands "such as salvaged or rebuilt title" among the factors that can lower the score. That's expected on a rebuilt car; the next question is how severe the original history was.
How much does an AutoCheck report cost?
As published on autocheck.com on November 12, 2026: $29.99 for one report, or $59.99 for 5 reports over 21 days, each a one-time fee.
Does AutoCheck or Carfax show how severe a rebuilt car's history was?
Not in a graded way. History reports record events and brands. A ReVroom Report adds an in-house severity grade, a severity graphic, an estimated savings percentage, and where and when the car was auctioned. It is not a vehicle history report and pairs with one.
