WhatsApp AI agent for used car dealers: answer the listing, qualify the buyer, book the test drive

A car listing on a portal generates twenty WhatsApp messages, most of them "still available?" and "lowest price?". The salesperson is with a buyer on the lot. By the time they reply, the buyer has messaged three other dealers. An AI agent answers the listing facts, qualifies the buyer, and books the test drive.

Quick answer

Put a WhatsApp AI agent on your dealership's number with a listing sheet (year, mileage, price, condition notes, availability), loan and trade-in information as published, and showroom hours as knowledge. It answers listing questions, asks budget, financing, trade-in and timeline, and books test drives. Negotiation, loan approvals and inspections stay with the salesperson. ReplyKit does this from $29 a month.

What the agent handles

Automate

  • Listing facts from your sheet: year, mileage, price, colour, ownership, condition notes, availability.
  • "Still available?" from the sheet, updated as cars sell.
  • Loan information as published: down payment, tenure, documents. No approvals.
  • Trade-in process and what to bring for a valuation.
  • Qualifying: budget, financing status, trade-in, timeline, saved to the lead's card.
  • Test drive booking into real slots, with a reminder.
  • Showroom hours, location, and warranty terms as written.

Keep with a person

  • Price negotiation and "lowest price?". The agent says the salesperson can discuss at the test drive.
  • Loan approval and eligibility.
  • Valuation of a trade-in.
  • Complaints and after-sales issues.

The listing sheet

One line per car: "2019 Honda City 1.5 V, 68,000 km, silver, 1 owner, RM 62,800, available." Replace the sheet when a car sells or the price changes; two versions in the knowledge base means either could be quoted. For "lowest price?", instruct: "The listed price is [X]. Our salesperson can discuss it with you at a test drive. Saturday 11am or 3pm?". The price list guide applies to listing sheets.

Setup for a dealer

  1. Use a dedicated number. ReplyKit connects your number through Meta's official WhatsApp Business Platform: keep the number you already use in the WhatsApp Business app and the agent works alongside it, or add a dedicated number. Personal WhatsApp numbers cannot be connected. Keep your long-standing number out of it; see Meta's messaging limits explained
  2. Upload the listing sheet and refresh it weekly or when a car sells.
  3. Write loan, trade-in and warranty information as text, exactly as published.
  4. Add test drives as a service with salesperson availability.
  5. Instruct the qualification and boundaries: no negotiation, no approvals.
  6. Connect the number through Meta's sign-in and test with "still available? lowest price?".

It explains published loan information and documents. Approval stays with the finance team.

Can it book test drives?

Yes, into real slots with a reminder.

How much does it cost?

How we know this. Dealers run ReplyKit against a listing sheet they refresh weekly, and the qualification sequence here is the one that gets buyers to a test drive.
