answer: #Person2# sold the old car because it gave #Person2# too much trouble and cost a lot of money. #Person2# is satisfied with #Person2#'s new car.
documents: #Person1#: Why did you sell the car?
  #Person2#: It gave me too much trouble. I was spending too much money on it. I was spending more money than it was worth. Unfortunately, of course, when you actually sell the car, you've already spent the money on it, so you lose both ways.
  #Person1#: Well, what was the trouble with your old car?
  #Person2#: The engine needed a lot of repairs and the wheels were giving trouble now and then. When I set off on a journey, it gave me a sort of feeling but I might not get to the other end. So I decided to change it.
  #Person1#: Is the new car good?
  #Person2#: Yes, it's newer, more comfortable and it hasn't given me any trouble at all. When I set off, I'm quite sure that I'll be able to get to the other end safely.
