text: Sofia: I think my car needs an oil change baby.
  David: Do you remember when was the last time you changed it?
  Sofia: I think it was when my car had like 30k miles on it.
  David: And how many it has now?
  Sofia: 45k
  David: Then yes, you definitely need an oil change
  Sofia: Should I do it at the dealer or a regular body shop?
  David: If you have a coupon you can make an appointment with at the dealer. If you don;t have it, it'll be more $$
  Sofia: I do have a 50% coupon sent in the mail.
  David: Then go ahead and schedule an appointment, maybe for Saturday that way I can take it if you want.
  Sofia: Perfect. I'll give them a call and check Saturday.
  David: Sounds good.
target: Sofia's car needs an oil change. Sofia will make an appointment for Saturday so David can take her car.
