I have a 2015 Fwd Sport with the 2.0 liter engine. It needs to have the door replaced on the passenger side as it hit a guardrail. I found a door that will work but to get a mirror for the door the guy asked me questions that I don't know the answers to. How do I find build date, if the mirror was heated, if it had blind spot monitoring? I just got the car and this is my first Mazda. I apologize in advance for the dumb questions.
