Rosalind's station wagon has the license plate 3Q49927. This plate shows up again in S5E3 on Lopez' tail car, and twice in S5E7 on a parked car at the Pico Drug stakeout, and later after Caputo is arrested.
The license plate 2FAN321 shows up on a miscellaneous SUV. It's also in S5E21 on a car that drive-by shooters use when they try to kill Frank when he's having dinner with Lucy, and in Destroyer (2018) on a miscellaneous car that is parked at an intersection when Bell is tailing Petra to the bank heist.
At 16.12 minutes in, as the police and FBI enter the alley, a filming car is visible. It is an adapted police black and white SUV with seat/steering/controls on the roof. These are covered by sheeting.
