CarFax has become the default tool for checking a vehicle's history — but for enthusiast cars, it misses the majority of what actually matters.
The Data Problem
CarFax works by purchasing data from repair shops, dealerships, and other service providers who opt into their reporting network. The problem is that most of the shops enthusiasts actually use — independent specialists, marque-specific workshops, trackday prep services, and private mechanics — don't report to CarFax at all.
That means a car with a full binder of receipts from the best independent Porsche shop in the country could show up on CarFax as having "no service history." The opposite of the truth.
What Gets Missed
Here's a partial list of what CarFax typically cannot capture:
For a daily driver with routine oil changes at a dealership, CarFax works reasonably well. For a 993 Porsche 911 with 30 years of specialist maintenance, it's nearly useless.
The Trust Gap
This creates a real problem for sellers. You've spent thousands on proper maintenance at the right shops, kept every receipt, and maintained your car meticulously. But a buyer runs a CarFax report and sees gaps — and assumes the worst.
The result? You either accept a lower price, spend hours convincing skeptical buyers, or lose deals entirely to cars with dealer-stamped service books that may tell a less complete story.
The AutoArchive Difference
AutoArchive was built specifically for this gap. Instead of relying on third-party data reporting, we let you upload your own documents directly — every invoice, receipt, inspection report, and parts record. Buyers see the actual paperwork, not a summary.
Every document is analyzed for authenticity, so buyers can trust what they're looking at. And because you control what's in your archive, nothing gets missed.
If you've been maintaining your car properly, AutoArchive lets you prove it.
