I'm expecting my new-to-me car this week and need to get the registration sorted out. I have the title in my possession and will complete that and pay taxes when I go to the DMV to get the car registered. However, I have a question about the smog requirements. The car is coming from MA and is a 2014 S4. Do I need to ask the seller for a copy of the most recent smog cert or do I have to get it re-smogged in CA?
