The camera pulls out to reveal 2015 BIFF behind a tree. He watches as 1955 Biff opens the car door and gets in.
Biff: Nah, you just gotta have the right touch. Nobody can start this car but me.
Terry: The bill comes to $302 and 57 cents...
Biff: 300 bucks?
He gets out of the car.
Biff: 300 bucks for a couple of dents? No, hey, that's bullshit Terry.
Terry: No Biff, it was horseshit, the whole car was filled with it.
We cut to 2015 Biff as he remembers this.
Terry: (v.o) I had to pay Old Man Jones 80 bucks to haul it away!
Biff: (v.o) Old Man Jones? He probably resold it too! Now I ought to get something for that.
Cut back to 1955 Biff and Terry.
Terry: You wanna get something for it? Well, go inside, you can call Old Man Jones and if you want us to give you a refund...
During the following Marty gets into the back of the car unseen and covers himself with a sheet.
Biff: It's 300 bucks Terry!
Terry: Look, I'm only charging you for...
Biff: If I catch the guy who caused this, I'll break his neck!
Cut to 2015 Biff as 1955 Biff and Terry enter the Western Auto Stores shop.
2015 Biff: The manure! I remember that!
As 2015 Biff walks off, 1955 Biff and Terry come out of the store. Biff pushes past a kid on a scooter. Terry is holding 4 cans. They're in the middle of their conversation.
Terry: ...4 cans of Valvoline is more than enough.
Biff: 4 cans for a $300 job?
Terry: I can't even have lunch in there, it makes me nauseous...
Biff: I should be getting a case or more out of you for a 300 buck job.
Terry: It smells worse than the bathroom!
They keep arguing as Biff throws the cans in the back of the car, where they land on Marty's sensitive bits!
Marty: Oomph!
Biff: (sarcastically, he's not really listening) Yeah, yeah, yeah...
Terry: The stench is never going to go away, Biff. Never going to go away.
Biff opens the door.
Biff: (sarcastically) Yeah, thanks a lot.
Terry: That's the last time I ever do you a favour! Last time!
In the background, LORRAINE and her friend BABS leave Ruth's clothes shop. They have a box and are laughing happily. Lorraine opens the box and pulls out the dress she will wear to the dance that night. Biff is watching them.
Babs: It's perfect Lorraine! You're gonna look so good!
Terry drives off as Biff goes over to the girls.
Babs: You're going to look...
Biff: Well lookie what we got here. Pretty nice dress, Lorraine.
Biff lifts up Lorraine's skirt.
Biff: Although, I think you'd look better wearing nothing at all.
Lorraine: Biff, why don't you take a long walk off a short pier?
Biff: Hey listen, Lorraine. There's that dance at school tonight. Right now, my car's all fixed. I'd figured that I'd cut you a break and give you the honour of going with the best-looking guy in school.
Lorraine: Well, I'm busy tonight, Biff.
Biff: Doing what?
Lorraine: Washing my hair.
Biff: That's as funny as a screen door on a battleship.
Cut to Marty in the back of Biff's car.
Marty: (under his breath) It's "screen door on a submarine," you dork.
Cut back to Lorraine, Babs and Biff.
Lorraine: Look Biff, someone already asked me to the dance.
Biff: Who, that bug George McFly?
