MISSDJ

I was selling a used car ( not running ). A guy calls and wants me to meet him about the car. He says he wants to buy it. He and a friend is constantly trying to jump it off and messing with things on the motor. Two hours go by and my patients is just about gone. They say they are going to the parts store down the road and ask if I'll wait for them to get back. Annoyed, I ask once again, "Are you going to buy this car?" They say yes and begin to drive away. Shortly after (about 5 minutes ) another guy drives up and wanted to buy the car. He showed me the money and said he only had a few minutes before he had to be at work. He had already looked at the car. Unsure what to do, I hesitated a minute. He said he had to go and asked, "Do you want to sell this car or not?" I sold it to him. Took the money and ran. Was I right??? Or just low down to the first guy???
