Ethical Dilemma

In this, the year 2007, we are all well versed in the finer points of Criag's list. It's the source of apartments, jobs, all sorts of encounters...We also know that we are not supposed to actually trust anyone. Only accept cash, don't deal with anyone outside of the area, etc, etc. Somehow I hit the ethical jackpot with my car ad. I have three people interested in my Honda-a Buddhist hospice worker, a teacher from the mid-west, and a doctor from Kuala Lumpur. I had really nice conversations with all of them. Now, I have ethical dilemma. How do you choose between the nice man from Malaysia, the Bronx teacher, or the hospice worker?

PS The doctor is a new driver...new like his license is one month old. It was a little nerve wracking to take him on his test drive. But, I'm sure he'll be fine.
