A Real Rain - S1-E17
Factual error: When BAU walks up the stairs on the way into the courthouse the first time, the John Ferraro building in Los Angeles is visible in the background. They are walking up the stairs toward Los Angeles City Hall. The episode takes place in New York.
Other mistake: During the flashbacks, they show Prentiss with the rest of the BAU, but Prentiss didn't join until season two. If it was accurate it would've shown Elle, not Prentiss. (00:19:49 - 00:21:01)
Visible crew/equipment: After the three people at the restaurant patio are shot it cuts to the black screen, and in the next shot as the camera pans over the blood stained table, the red T-mark is visible on the ground in front of Gideon's feet. (00:13:15)
Visible crew/equipment: During the plane interior scene after the opening credits as JJ is walking around handing out documents to the team, you can see a gap in the lighting outside and a crew member's face peeking out from behind the white walls. (00:04:00)
Empty Planet - S2-E8
Other mistake: In Empty Planet where the exploded bus is shown, there is an evidence marker with blood spatters on it. The blood wouldn't be there if the marker was placed after the event had occurred.
Other mistake: When Stephen looks at his phone you can see the phone charging symbol even though the phone he's holding isn't charging. (00:06:53)
Character mistake: In the meeting room, there's a clear spelling mistake of "Manditory" in bold letters on the whiteboard behind Gideon. Flashes up there several times during the scene. (00:16:00)
Visible crew/equipment: You can see a crewmember's hand as she runs through the tunnels. (00:24:57)
Continuity mistake: When Gideon, Morgan, Reid and Greenaway are watching Hotch interrogating the suspect Tony Canardo there is a box on the table, then Hotch gets up and walks out of the room and the box on the table is gone. In the next shot on the TV the box has reappeared. (00:30:08)
Continuity mistake: When Gideon is talking when we first see him, the pictures behind him on the screen change instantly. It should be noted, that when we see the pictures change, there is the audible click and visual delay of a slide change which is not present on the instant change. (00:04:20)
Continuity mistake: Morgan gets a call from BAU and we see him holding his phone in one hand then two. (00:03:40)
Target Rich - S11-E7
Character mistake: When the unsub puts the lock on the woman's collar, he hooks it onto the part where a leash would go. She could easily take the collar off. Later, the lock is on a different hook that is pushed through the collar, so she would not be able to escape. (00:19:10 - 00:33:30)
Character mistake: When Reid and Rossi propose the theory that Kate knew Syd and Jimmy before her disappearance, and JJ expresses her skepticism, Rossi retorts "they're handsome, charming, 19." But while reviewing the case on the flight to Maryland, JJ mentions that the boys are both 20.
Continuity mistake: When the pregnant lady came in with her child saying her 8 year old Matthew was missing, JJ sits her down and says she has a niece who is 8. We later learn that JJ's only sibling was her sister who committed suicide and who didn't have any children.
Continuity mistake: When the thief tries to steal the truck and the owner is beating him up, the passenger window behind the driver breaks. When his daughter later gets into the truck, very briefly the window is not broken. Then the next shot shows her in the truck, the window is broken again.
Continuity mistake: The same flashback of Roslyn Jareau giving her necklace to JJ is shown twice, but their dialogue is slightly different the second time.
Continuity mistake: Reid moves his gun to his side after the militia tell him he is begging for someone to take it. You can see it after they send Morgan to the bar. One second it's on his side, the next second it's back in front off his hip like always. (00:23:15)
Continuity mistake: While George Foyet is stabbing Agent Hotchner, the knife is extending from the handle. The blood is at the top of the blade, and as he removes it, the blood moves to the bottom of the blade, while the top remains clean.
Audio problem: As Scott McCarty is shot there is no sound of a shot being fired, suggesting a silencer, however as the assailant's rifle is pulled inside the car you can see that the weapon has no silencer.
Revealing mistake: We see the jet at the end, and the shot is flipped. Note the serial number on the plane's engine. (00:38:05)
Chosen answer: Black SUVs are common police, military and dignitary vehicles around the world. It is not too much to assume they could be rented or owned by the police forces in the areas.

Other people have explained it but fore more information, federal cars would most likely be brought to the airport from the nearest agency, so they can drive out to their locations especially in rural situations.
