"Carfax" type visibility for potential laptop buyers

If you are thinking of buying a car, you can pay Carfax to show you provenance information about a car. It saves you from having to contact every state DMV to make sure the car wasn’t totaled in some state from a hurricane.

If someone is thinking of buying a laptop, they would want to see a certificate of authenticity, and that it was wiped properly, etc.
How much of that information should be accessible?
How much should be private?
