Same car, same verdict
Consistency across sites is not a nice-to-have: it is what makes a price comparable.
Ask two inspectors to assess the same car and you will often get two different reports. The difference is rarely bad faith; it is the method.
For a dealer group, that inconsistency travels straight into prices: the same model is valued differently depending on the branch that took it in.
Because DeepDiag measures behaviour with the same road test and the same models everywhere, the verdict depends on the car, not on who drove it.
That consistency is what lets Steer Autos compare cars across sites, and what lets a buyer trust a report made somewhere else.
These notes describe the method in general terms. Findings in a report always come from the car's own road test.
