The rock. Let me have it

Jim Douglas:

I, I hate to mention this again... but I heard some clunking... Wheely Applegate:
You mean that nonsense about the gas tank? Jim Douglas:
Yeah, That's... Wheely Applegate:
All right, let's get it straight, once and for all... who the mechanic is around here, okay? You say it's the gas tank, and I say It isn't the gas tank. You see? It isn't the gas tank. It's this... rock that was in the gas tank. [Clears throat] Jim Douglas:
Hold it! There's only one kind of rock that glistens like that. Wheely Applegate:
Well, sure, quartz. You can find millions of'em around any quarry in Philly. Jim Douglas:
But... not one that's worth... 6,000,000 bucks. Wheely Applegate:
Huh? Jim Douglas:
L 'etoile dejoie. Wheely Applegate:
The tall, the what? Jim Douglas:
Etoile dejoie. Wheely Applegate:
[Gasps]
Oh, wow! That's... [Gasps] Wheely Applegate:
That's the biggest hunk of diamond I've ever seen in my life. Jim Douglas:
What I don't understand is how it - The black sedan! Wheely Applegate:
Huh? Where? Jim Douglas:
No, no, no. They're the ones that robbed the museum. Don't You see? They weren't trying to knock us out of the race. They were trying to get this out of Herbie. Max:
[But suddenly coming behind]
Thank you for helping us, gentlemen, and up with your hands. Quincey:
You gave us the slip for the last time. Max:
We'll take the rock. Wheely Applegate:
[Clearing throat]
I don't suppose you'd believe that was just a big hunk of quartz. Max:
[Chuckles]
