Reunited and it feels ok

So yesterday morning I dropped off my car to the dealership so they can investigate the check engine light. Diagnostics run at about $150. None of that goes into parts or labor. They called me this morning (waking me up) and told me that they figured out what they need to do but they need a part. That part won't be coming in until Monday. Once they get the part they'll call me to schedule an appointment to get the work done on it. The good news, I don't have to pay a single cent. I LOVE WARRANTIES
