Joint entry, since both operate dealer-only and reach consumers indirectly through the used cars on retail lots.
Manheim — claims to be the wholesale market's reference venue; verified trivially, as its MMR figures function as the industry's price index. Dealer-license gating, condition-light arbitration and announcement rules are documented and enforced. For consumers the index notes one use: MMR-anchored negotiation on retail prices.
ACV Auctions — claims app-based wholesale built on staff-performed inspections; verified via its published inspection standard (paint readings, undercarriage imagery, OBD data, engine audio) and arbitration tied to report accuracy. Consumer-side use: asking a retail dealer for the wholesale condition report on an auction-sourced unit.
Disposition: both established; both irrelevant to consumers directly and highly relevant as leverage. Any retail service claiming to “get you into” these lanes is operating a brokered-license model — index that intermediary separately, as we do with auction purchase services elsewhere in this section.
