In my last job, the biggest challenge I faced still actually haunts me today, and it was years ago. We had two similar vehicles that were about the same year, same look, different VIN, same mileage. I sold the wrong car to a customer, and I was the one that found out that it was the wrong vehicle, so I owned up to it. I went up to the managers, told them, called the customer myself, explained to them the situation. They were very upset, still handled it, made sure that they were happy. They came in, we got them into another car, but I handled it. They were still upset, but I made sure that I was here for them throughout the whole process. Even if it was my fault, I still owned up to it, wanted to make sure everything was right, made sure they left happy, made sure the management was happy. I did lose some money in the process, but I still was able to make sure that the customer was happy, and that's all that mattered to me.
