When you turn your car over to a mechanic, you really have no idea what  they're going to do.  Since no one wants to go joyriding in a 1996 Saturn,  you're probably safe.  But people with more EXCITING cars might not be.

William Clark of Easley, South Carolina drives a 2010 Chevy Camaro SS.   This is his second Camaro . . . his last one died after he left it with a  dealership for servicing.  He suspected they messed with it, but didn't  have proof.

So when his new Camaro started making a clicking sound during stops, he took  it to a different dealership called Best Chevrolet-Kia in Easley, South  Carolina, and hid a TAPE RECORDER in the glove compartment.

And his worst suspicions came true.  On the tape he could hear the  mechanics joyriding in his Camaro, doing BURNOUTS . . . and destroying his  clutch.

THEN he heard them talking about whether they could trick William into paying  for the clutch.

He played the audio for the dealer, but they only offered to reassess the  damage.  Chevrolet's customer service said it wasn't their problem, it was  between him and the dealer.  So William decided to post the audio on YouTube.

And NOW he's got their attention.  He says the dealership is threatening  to SUE him over the audio because it's, quote, "misleadingly edited."  But  he also says they've talked to him about buying the car back from him.
