CARFAX vs AutoCheck vs ClearVIN: Which one should you choose?

When buying a vehicle history report, you'll run into three main options: CARFAX, AutoCheck, and ClearVIN. All three provide useful information, but their strengths differ — which one makes sense depends on what you actually need.

CARFAX — the most detailed accident and ownership history

CARFAX offers the most detailed report when it comes to accident history and ownership history. Service records are also shown in depth. If a vehicle's past accidents and number of owners are your top priority, CARFAX is the strongest choice.

AutoCheck — a unique scoring system and fast evaluation

AutoCheck's standout feature is its AutoCheck Score — a system no other report offers. It condenses a vehicle's overall history into a single number, making quick comparisons easier. It's also reliable for odometer checks and ownership history.

ClearVIN — strongest for auction history and Canadian data

If you're buying from a US auction (Copart, IAAI), ClearVIN is particularly useful — it shows the most detailed auction history of the three. It's also the strongest option for Canadian vehicle data.
