Okay I'll join with Case Cracker. His cutie mark are hoofprints which represent his ability to track items and other creatures if needed (with enough evidence to know what he is tracking)

Here is his car for this situation

I'm using Gordon

This is Gordon's car.

The roleplay begins with Gordon, and Case Cracker at Gordon's house. They are watching a football game. The Eagles are beating the Giants 21-10

Gordon: I always told you that the Giants sucked.

Case Cracker: Calm down, halftime just ended. They've had some bad luck is all

Gordon: No kidding. They'll never win a game.

Suddenly, the phone rings.

Gordon: Ah good. Commercials, and a call. *picks up phone* Hello?
Jim: Hey Gordon, it's Jim. Get Case Cracker with you, and meet me at the Pizzeria on Mane Ashbury.
Gordon: Alright. We're on our way.

CC: *grabs glasses as he is leaving*

Gordon: *Turns off TV* Let's take your car.

Gordon: *walks out door*
Postman: Mornin' Gordon.
Gordon: Hello. What have ya got?
Postman: The usual bills, and a letter from this mare I don't even know.
Gordon: Alright, give it to me, I'll put it in my house.
Postman: *Gives Gordon his mail*
Gordon: *puts mail in house*

Here the Cupcake Sprinkles you wanted.

Here,

*readys car*

Gordon: *gets in car* Let's do this.

CC: *starts car*...*drives to pizzeria*

Gordon: *turns on radio*
News Reporter: This just in, the Rock Island Biker gang has attacked again. As a family of four were driving across the Golden Neigh Bridge, the Rock Island bikers shot up their car, and stole all the money in there.
Gordon: I hate those fucking bikers.

One minute later, we arrive at the pizzeria

CC: *enters pizzeria*
What cha' got for us this time Jim?

Jim: I've got a load of cocaine that needs to get safely to the airport. Unfortunately a friend of mine is very obsessed with that shit in Manehattan.
Gordon: This is pretty serious.
Jim: Yes it is. I've got a Lunicorn in the parking lot with the drugs, you just gotta get it to the airport, and collect the money.

CC: An' what are the terms?

Jim: Just get it to the airport, and give it to the pilot of this green aircraft. He'll pay you seven thousand dollars. Once you get the money, just come back here, and give it to me.
Gordon: Ok, we got it.
Jim: *gives keys to Gordon* Here are the keys to the car, and be careful.
Gordon: You can count on us Jim. *leaves*

CC: *settles into passenger seat*

Gordon: *starts to drive* The airport shouldn't be far away. Turn on the radio if you'd like.

CC: *turns on radio and begins to search for a station*
Sounds like a lotta static

Gordon: *stops at red light* Let me try. *turns onto 98.1* This radio station has a lot of rock & roll, but right now they're playing a commercial.
Announcer: Behold, the best cars you could ever ask for, from Chevronet. Chevronet has made many enjoyable cars, from the Belair to the Corvette. From the Station Wagon to the Pearla. All four are great cars, because they're made by Chevronet.

(I'm going to let you choose a song)

*commercial ends* *born to be wild begins to play*

Here's the song you have chosen

*rolls down windows and turns the music up*

Mares: *Staring at Case Cracker*
Gordon: You're getting a lot of attention.

The light turns green

Gordon: *driving 36 miles an hour*

CC: *switches glasses to dark shades as they drive away*

Gordon: *Turns right*

A police car is about to pass us

Gordon: Oh damn.

CC: oh, buck...

Police: *pass*
Gordon: Oh thank christ. For a moment, I thought they'd arrest us for the crack. It's a good thing we're near the airport.

CC: Yeah, we can't draw attention to ourselves...

Gordon: Hey, I'm just following the speed limit.

Soon we arrive at the airport.

CC: So, this is the place

Gordon: Yep. Now we got to find a pony with a green airplane.

CC: *casually trots through the airport looking for the correct airplane*

Gordon: *Slowly driving around airport* Aha, there it is.

Gordon stops the car, and the pilot of the green plane comes out.

Pilot: You got the cocaine?
Gordon: Yeah. Case, open the trunk, and bring the cocaine to him.

CC: *walks over with case*...*opens case for pilot to see*

Pilot: *looks at cocaine* Ah excellent. *takes drugs* Here's your money. *pays seven thousand dollars*

CC: Cool, now we've just gotta get it back

Suddenly, a police officer sees us

Police: Freeze!! Put the cocaine on the ground right now!
Pilot: You guys go! I'll cover you!
Gordon: *gets in car*

CC:*while running to car* (To cops) Buck NO!

Aw, what the hay. I'll join in.

Power Play: *jacks the crack, puts it in his Foalarri (or whatever the buck it is) and takes off to Jim's location* If you want this shit, you gotta fuckin' catch be first, you fuckhead cops!
Police: Holy shit! All units respond! Suspect has been changed to a dark blue pony with a game controller for a cutie mark! Suspect is driving a raven-black Foalarri!
Power Play: I hope to Celestia the $2,500 I shelled out for nitrous on this thing pays off...
*made it to Jim's location before the police made it; hightails it inside, cocaine in hoof, and puts it on the desk Jim sits behind*
Power Play: Sorry I'm not who you expected to be here. Your original ponies that had to deliver this shit to wherever it had to go got caught by the 5-0. Now if you excuse me, I gotta ditch 'em myself. *bolts it to the car and takes off to Candlestick Park, home of the 49ers*

Pilot: Aw damn it! He took the fucking drugs!!
Gordon: *Drives away* Who the fuck was that guy?

Gordon: *driving back to Mane Ashbury* The only good thing was that he got rid of the police.

CC: Yeah, cuz' I am not going back to a cell

Gordon: Jim is not going to be happy when he hears the cocaine was stolen.
