Milestones - S9-E12
Other mistake: First we see Jamie in a Ford CVPI with license plates 7554 like a couple of times before in the show, a minute after he's seen exiting a 2015 Ford Taurus with plates 82399. He answers a 10-85 while supposedly driving in the CVPI but somehow he manages to change in less than a minute to a Taurus. We see the exterior of the car, but the car's interior corresponding to the Taurus is seen a few seconds earlier. (00:03:35 - 00:04:20)
