I recommend one thing. don't go there saying you are there to buy the vehicle. People get very defensive and closed off. Tell her you are there to hear the history of the car, or something similar. That puts people in an very different mood. Usually people want to tell the stories of the stuff they own, things they remember from the past, etc... Later, mention that you would do anything to make sure the Cuda was safe, and if you could help in any way, wash, clean, buy, the car that you would be interested.
That's how I've been able to see so much, ask for the story.
