Goofs

When Mike meets Stacey at her house to babysit Kaylee, the license plate on her Subaru appears, disappears, and then reappears in between shots.

Compounding the license plate continuity errors with Stacey Ehrmantraut's car, there is also the issue that it is clearly not a New Mexico plate. It appears to be a Pennsylvania license plate. Even though the seasons do not align to calendar years, Stacy has been living in New Mexico for years at this point in the fifth season. Maintaining out of state plates on her car after living in the state for such a long period of time would mean she is liable for fines for failing to register her vehicle in New Mexico in a timely manner. Beyond this, there is no way should could have (legally) renewed out of state plates as a resident of New Mexico and so, presumably, these plates must be expired.
