Holley Shiftwell is Finn McMissile's assistant. And Tow Mater's beloved girlfriend. In AppMates, when you make her bodge a tumbleweed, she says "They don't get many tumbleweeds in London."
In Cars 2, Holley Shiftwell is an American desk agent, who was sent to Tokyo to exchange important information to Finn McMissile. Unexpectedly, she was commanded into a field agent, and helped solve the mystery of the engine. At the end at the movie, she says she is Mater's girlfriend and says to Mater that he still owes her a first date.

An alternate costume of her, Racer Holley, can be unlocked by earning the "Agent - Second Class" crest.

Kinect Rush: A Disney/Pixar Adventure
In Kinect Rush: A Disney/Pixar Adventure, she appears in the first Cars level in the end-scene, which she answers that the player is indeed going to be a great addition in Lightning McQueen's racing team, which she explains that she was observing the whole time and that was a most impressive display. Mater then introduces the player to her, explaining that she's his girlfriend. She then says that the player would make an excellent racer, but an even better spy, and they have a mission that is perfect for the player's speed and talents, which she then says that is if Lightning doesn't mind waiting, before Mater says that he can, before asking him, which he answers, "Well, who am I to interfere with British Intelligence?" Holley also appears in the second level, played by one of the kids in the park. The mission takes her and the player to Tokyo, where somebody planted a bomb somewhere on the course of the Tokyo Grand Prix. Holley has a bomb detector, and the player has a new device that can disarm the bomb, but only works at very short range. So Holley and the player have to seek the course, find the bomb and get close enough to deactivate it before it explodes. The detector shows the signal near them, which Holley says that it must be somewhere nearby, before Francesco Bernoulli races past them, telling them to keep off the course as he has a race to prepare for. They then discover that the bomb was put on Francesco, who doesn't even know about it, which the player has to catch him and deactivate it. In the end-scene, Holley tells the player that she sees the bomb, and then the player deactivates the bomb, which then comes off Francesco. While Holley and the player investigate the bomb, Francesco asks them what do they want with him. Holley explains that they had no choice because that someone sabotaged him with the bomb, but he's safe now. However, Francesco doesn't believe it, saying that it is ridiculous and that he is not easily fooled, before he drives off saying that they are just trying to get into his head, but it will never work. Holley says that she doesn't know why not, and that it sounds like there's plenty of room in there, before using a gadget from her undercarriage to pick up the bomb, saying that she'll get their technicians to work analyzing/analysing the device immediately. She is also heard in the other levels when the player unlocks a new weapon that is wings for flying, which she tells the player to do gliding when a ramp comes up.
In Disney Infinity, Holley is one of the four playable characters representing the Cars franchise, her figure being included with Lightning McQueen in the Cars Play Set pack. She is capable of doing everything the other cars can do, including towing, doing tricks, boosting, and powersliding. In toy box mode, her unique adventure is Holley's C.H.R.O.M.E. Course, in which the player must destroy a variety of enemies in order to earn a medal.

As a spy, Holley Shiftwell is equipped with gadgets including:
On-board computer: Holley is equipped with a computer that can analyze spy data. It projects a hologram heads-up display as a screen and dual trackball platforms as a mouse.
Projection lamps: Located above her headlights, they emit the hologram heads-up display.
Dual mounted trackball platforms: Retract in the undercarriage and used to control the heads-up display, with the wheels, in the way a mouse controls a computer.

Digital read-outs: Located on the side mirror, the screen can receive transmissions from other spies or view a map of the environment.
Retractable wings for flight: Holley has wings that protrude from her rocker panels and her rear deck lid becomes a horizontal stabilizer of a rear wing that has a jet intake. Afterburners appear in her exhaust.
Holley's front wheels are equipped with several gadgets:
Concealed guns: One in each front wheel.
Electroshock device: A taser-like weapon. Holley uses it to neutralize cars without damaging them.

Holley Shiftwell: "This cannot be him." Finn McMissile: "Is he American?" Mater: "Look out, ladies! Mater's fittin' to get funky!" Holley Shiftwell: "Extremely." Finn McMissile: "Then it's him." Holley Shiftwell: (drives over to Mater) "Hello." Mater: "Well, hello!" Holley Shiftwell: "A Volkswagen Karmann Ghia has no radiator." Mater: "Well, of course it doesn't! That's 'cause it's air cooled!" Holley Shiftwell: "Perfect! Erm, I'm from the Tokyo station." Mater: "'Course, Karmann Ghias weren't the only ones. Besides the Beetles, you had your Type 3 Squarebacks with the Pancake motors." Holley Shiftwell: "Yeah, okay. I get it." Mater: "And before both of them, there's the Type 2 buses. My buddy Fillmore's one of them." Holley Shiftwell: "Listen! Erm, we should find somewhere more private." Mater: "Uh... Gee, don't you think that's a little. . .?" Holley Shiftwell: "Yeah, you're right. Impossible to know which areas here are compromised. So, when can I see you again?" Mater: "Well, let's see. Tomorrow I'll be out there at the races." Holley Shiftwell: "Got it! We'll rendezvous then."
