I would bet that an enterprising stealership would be able to say something like “How could we have known the previous user tampered with the emissions and powertrain programming, they did not disclose this to us”. Were I a scummy stealership in PA, I’d probably be inclined to interpret this broadly and provide a less precise, more general previous use description to “operated on public roadways” to be compliant. I’m not saying this is ethical, just a way I could see a stealership to exploit the law.
There are two groups of people in the populace who exist because
1) they excel at deception, whether by explicit action, selective use of language or omisison
2) their command of language and manipulative skill make them superior to most other people’s ability to detect deception
They are politicians and vehicle sales men/women.
Even a good and practiced negotiator can fall victim to people who are comfortable manipulating others.
