Turn live inventory into
attributable buyer opportunities.
Listings are posted by named dealership employees from their own accounts under written manager approval, fed by a read-only import of your inventory. Quantum maintains the listing lifecycle, captures buyer inquiries, and carries each opportunity into Hannah, human handoff, and CRM writeback.

Marketplace is not the final product. It is where the opportunity begins.
A listing alone does not create dealership value. The value appears when accurate inventory reaches the right channel, a buyer responds, the conversation is worked, a salesperson takes ownership, and the result is recorded. Quantum connects that complete path.
Accurate Inventory
Current vehicle, price, photos, mileage, availability, and dealership disclosures.
Controlled Distribution
Approved listing workflows with account, channel, volume, and policy controls.
Attributed Inquiry

Every listing is written to the FTC standard and your state rules.
All-in pricing is the federal enforcement standard, and the states add their own requirements on top. Pick your state to see what a listing has to say.
FTC enforcement update, March 2026
The FTC sent warning letters to 97 auto dealership groups on March 13, 2026. The CARS Rule was vacated in January 2025, but Section 5 of the FTC Act is fully in force, and all-in pricing is the federal enforcement standard.
Required in every listing, all 50 states
- Accurate year, make, model, trim, mileage, VIN, and availability
- All-in advertised price that includes every mandatory fee, with taxes and title excluded only
- The advertised price must match the price actually charged
- Conditional rebates must disclose their eligibility requirements
- If finance terms are advertised: APR, term, monthly payment, down payment, and total of payments
- The dealership name must appear on the listing
- Add-on products and fees cannot be hidden or added after the listing
- No bait and switch. The advertised vehicle must be available at the advertised price
Never used in a listing
- Guaranteed Approval or Everyone Approved
- No Credit Check
- $0 Down without full financing terms disclosed
- Lowest Price Guaranteed without qualification
- Free without the conditions clearly stated
- Fake or inflated MSRP discounts
- Pricing that requires dealer financing to achieve
- Hidden doc fees, processing fees, or add-ons left out of the advertised price
Your state rules
State requirements apply on top of the federal baseline above.

- Any edit to a live listing triggers a new compliance validation
- Listing history is retained for at least 24 months
Source: Quantum Connect AI 50-State Automotive Advertising Compliance Reference Guide, effective May 2026. This is a compliance reference framework for operational guidance, not legal advice. State rules change often. Dealerships in the highest risk states should have automotive advertising counsel review current listings.
Every listing begins with inventory you can trust.
Quantum converts incoming inventory data into one consistent vehicle structure before it reaches a distribution channel.

If required information is missing, stale, conflicting, or outside dealership policy, Quantum holds the listing for review rather than inventing or publishing uncertain data.
Every listing has a visible operational state.
- Ready
Vehicle passed validation and is eligible for the configured workflow.
- Queued
Listing is waiting for an approved account, schedule, or volume window.
- Published
Listing is live and connected to its vehicle, account, rep, and source.
- Update Pending
Vehicle details changed and require synchronization.
- Attention Required
A field, policy, account, or channel issue requires review.
- Paused
Distribution stopped by dealership rule, system health, or operator action.
- Sold or Removed
The vehicle is no longer available and removal is being tracked.
- Expired
The listing reached its channel lifecycle limit and requires an approved next step.
Every status change creates an event with a source, timestamp, owner, result, and recovery path.
Know when distribution is healthy, and when to stop.
Quantum monitors the operational conditions around each configured account and channel workflow. When a material problem appears, the system can pause affected work instead of continuing silently.

Quantum does not use automation to bypass platform access controls. Every deployment must follow the dealership’s authorization and the channel’s permitted operating method.
Every buyer message stays connected to the vehicle that created it.
Quantum captures the source and context required to continue the opportunity without forcing the buyer or salesperson to start over.

Before creating a new person or opportunity, Quantum searches for an authorized existing match and records uncertainty instead of forcing a duplicate.
The buyer should not have to repeat the vehicle they asked about.
When an inquiry enters Quantum, Hannah receives the approved vehicle context, dealership rules, conversation history, response authority, and current human ownership state.
Hannah may
- Acknowledge the inquiry
- Confirm the vehicle of interest
- Answer verified vehicle questions
- Understand timing and needs
- Offer approved alternatives
- Request the next useful detail
- Schedule a verified appointment
- Escalate uncertainty to a human

When the salesperson takes over, Hannah steps back.
Quantum records the transfer of ownership so the buyer never receives competing messages from the AI and the human sales team.

Marketplace activity becomes dealership record, not a disconnected transcript.
Quantum writes authorized opportunity facts back through the available dealer-approved connection.

Every write is timestamped, attributable, idempotent, retryable, and reconciled. If a write fails, Quantum records the failure and follows the approved recovery path rather than pretending the update succeeded.

Common questions.
Does Marketplace Engine require a new inventory system?+
No. Quantum is designed to receive dealership-approved inventory feeds and normalize them into its listing workflow.
Does Quantum guarantee access to Facebook Marketplace or any third-party channel?+
No. Availability depends on the channel, account, dealership authorization, permitted operating method, and platform rules.
Can one salesperson manage multiple listings?+
Yes, within the configured account, volume, operational, and channel constraints.
What happens when a vehicle sells?+
Quantum records the inventory change and initiates the configured listing-removal workflow. Removal status remains visible until confirmed or escalated.
How are inquiries sent to the CRM?+
The available method may include a certified API, dealer-authorized API, webhook, ADF/XML, managed integration, or approved export workflow. The exact read/write capability is documented for each system.
Does Hannah automatically respond to every inquiry?+
Only when the dealership has authorized the workflow, the buyer and channel state allow it, the required context is available, and no human currently owns the conversation.
How do dealerships post cars on Facebook Marketplace?+
Quantum supports a governed workflow where named dealership employees post from their own accounts under written manager approval, using a read-only inventory feed and approved daily windows.
Can AI respond to Marketplace car leads?+
Yes, when the dealership has authorized Hannah to respond, the buyer and channel state allow it, and the vehicle context is available.
What are the rules for advertising cars on Marketplace?+
Listings must use accurate vehicle information, real photos, truthful pricing, and required disclosures. Quantum includes an advertising compliance module with federal and state-level guidance.
How do you keep dealership inventory accurate online?+
Quantum receives a read-only inventory feed, normalizes vehicle data, validates required fields, and updates or removes listings when the feed shows a change.
Can AI post vehicles to Marketplace for a dealership?+
Quantum does not post from anonymous or business accounts. Listings are published by named dealership employees from their own accounts under manager approval.
