Start with genuine curiosity. Ask how long they have owned it, what they loved, what changed, and which repairs were recent. Compliment maintained details. People sell to people, not spreadsheets. Connection reveals helpful truths like spare parts, extra wheels, or pending issues they forgot to mention online.
Walk through findings calmly, tying each note to time or cost. Share a printed list to reduce defensiveness. Then present an offer that solves their problem today. If they hesitate, ask what would make it easy, and pause. Silence invites fairness better than pressure.
Scarcity noise, rushed meetups, missing documents, or evasive answers signal danger. Thank them, wish luck, and depart. Text later with a polite, firm number if interest remains. You will rarely regret walking, but almost always regret ignoring your gut when red flags flutter loudly.
