I would be as interested in the seller as in the car. By comparison, if I was looking at a Cobra with 7-10k miles on it and it was owned by someone that didn't have a clue about the car, how everything worked, what has been fixed etc and how to work on it I would be suspect.
On the other hand, same car from a knowledgeable seller who talks you ear off about all the things he has fixed and how he has maintained it would make me much more comfortable.
