So you find an interesting prospect car but its 1000 miles away. What are the most important questions to ask over the phone? If "rust free" is your major issue, do you belabor the point by asking about floorpans, cowls, blisters etc to the point it becomes uncomfortable? OR, do you call the guy in a neutral posture and check out the car in a less threatening way by asking general questions? What approach do you guys use? Do you prepare a list of questions beforehand?
