1 hour and 5 min appointment

So my wife called the dealership to make an appointment this upcoming Saturday for an oil change as well as the recall repair. The phone rep told her we will not get a loaner because the repair will only take 1 hour and 5 mins even though the letter stated 4 hours/half day. I know..... odd time estimate, but oh well. We will just go in and wait around until it is done.
