Meta's Muse agent can now find a used car on Facebook Marketplace and haggle for you. Nothing checks the car. Private sellers ask for deposits on cars that don't exist, and a strip of tape over the check-engine light hides a fault. The people hit hardest are students buying a cheap first car, often international students with no one to bring along to look at it.

TireKick is a buyer's agent in WhatsApp that makes the car prove itself before anyone talks price.

1. The buyer pastes a listing and their max price. Muse Spark reads it; code checks that the price is really in the text and the VIN is valid. Muse Spark's web search finds similar cars, and only prices with a source link count.
2. The seller gets a one-time code and films one continuous take: the code next to the windshield VIN, the door-jamb VIN, every warning light at key-on, the odometer, then the engine start.
3. Muse Spark watches the video three times and reports what it sees. Code then runs 13 checks: the code matches, no cuts, not filmed off a screen, the VIN passes the check digit and matches the door and the listing, the NHTSA decode and recalls, every must-light comes on, nothing stays lit after the start, the odometer matches, a cold start, scam phrases in the chat, and a price far below market.
4. The verdict (don't buy / negotiate with care / looks clean) is computed in code, never by the model. The buyer gets a report page with a still frame for each finding, highlighted with SAM 3.1.
5. TireKick negotiates. Prices come from code and never exceed the buyer's max. Muse Spark writes the words, and every draft is checked: it may only cite verified findings, can't invent prices, and can't ask for deposits, payment details or addresses. The buyer approves every message. When the seller agrees, it suggests a police-station safe exchange zone.

Results (no real car was available, so video tests used AI-generated clips and the negotiation study used AI-played sellers):
- Red team: 6 of 6 spoof attempts caught (AI-generated take, old video or wrong code, a different car). Anyone can re-run it with six commands from the README.
- 60 simulated negotiations: TireKick got 84% of the possible discount vs 51% for a student alone, and closed 30/30 deals vs 15/30.
- 200 public listings: 96% are a model with at least one NHTSA recall.
- Our miss: 0 of 3 hidden check-engine lights caught at first, because "can't tell" counted as a pass. We fixed it (an unconfirmed light is now flagged and the seller is asked to refilm); it isn't re-measured yet.

A full verification runs in about a minute with the real models. Our WhatsApp business number is waiting on Meta business verification, so the demo runs the same bot in a browser chat (WhatsApp and Marketplace/Messenger styles). TireKick is not a mechanical inspection, never moves money, and always tells the buyer to get one before paying.
