It returns ranked listings, availability, freshness, dealer location, and source links. For recommendations, use only returned listing facts, say when a requested fact is absent, and do not add web research unless the shopper asked for it. Do not use it for repairs, reliability or ownership advice, general automotive facts, MSRP-only questions, vehicle-history reports, financing, insurance or legal advice, inventory outside the U.S. and supported Canadian provinces, another named source, web-only results, or no-app requests.
