Manheim is where franchised and independent auto dealers trade used cars at wholesale, and its Market Report (MMR) is the de facto price index for the trade. For our readers the entry matters in two ways:
- Directly: access requires a dealer license. If an online service offers you “Manheim access,” you are buying through their license — ask who arbitrates and who holds the title in the interim.
- Indirectly: MMR is the floor under every retail used-car price. A retail asking price far above MMR plus reconditioning is a negotiation opening, not a law of nature.
Trust profile: as established as it gets in this industry — the caveats are all about access mechanics and the professional pace of its arbitration windows, not legitimacy.
