Apparently, renewing my car registration this year required a smog check. I missed that detail and got a DMV notice that the payment had been received and not the smog certificate. So, I immediately brought my car to Doral's and requested a smog check. They graciously accepted it and asked if anything else was needed and I replied, "no". Well, apparently, not only do they not do smog checks, there are different types and the necessary one is indicated on the registration renewal form which I didn't have to show to them. No biggie for them; they had a way to find out. They always come through for me.
