Most buyers have something to trade, and the number is often what decides whether they engage at all. The agent collects the details and returns a market-based estimate without the buyer leaving the thread. A chat conversation collecting vehicle condition, VIN, and odometer reading for a trade-in ## What it asks for * **Condition** — Excellent, Good, Fair, or Poor * **VIN** * **Odometer reading** * **Contact details** — name, phone, and optionally email Condition as a simple four-way choice is deliberate. Asking a buyer to self-assess in more detail than that produces worse data, not better. ## Why it matters for your team A trade-in estimate is one of the strongest qualification signals you can get. It tells you the buyer is serious, and it gives your rep a number to work from before the buyer walks in. The valuation and the vehicle details land on the lead, so whoever picks it up sees the trade context alongside the rest of the conversation. The estimate is a market-based indication to move the conversation forward, not a committed offer. Your team confirms the final number after inspecting the vehicle. Review trade details on the lead.
