My car needs inspection once a year. I am off of work tomorrow and was going to get that done then, but my car broke down this past weekend (minor, but I can't fix it myself) and my mechanic is on vacation ! The car won't pass inspection until it is fixed, so my plan to do it tomorrow is no longer a plan. Fortunately I still have a few weeks before it is due, so hopefully it will get repaired in time.
I don't usually call for an appointment, I just go early and most of the time there is nearly no one there and it goes pretty fast.
It sounds like you had quite the busy day!
