ROWLETT (CBS11) – “Leave the keys in the car!”

That’s what a busy auto shop told one family to do, and it nearly cost them their SUV.

18-year-old Richard Cabral has been saving up to buy his father’s Trailblazer for college.

He took it to Kwik Kar on Lakeview Parkway in Rowlett Monday morning to get an inspection.

Cabral says he left the keys on the dashboard, as an employee requested.

Minutes later surveillance video shows someone walk to the back of the business, get in the vehicle and drive away.

Cabral was waiting in the lobby when an employee came in.

“And they’re like, ‘Where’s your car?'” he recalls. “I was pretty angry, me and my dad both and we were kind of in disbelief the car was not there.”

At 2 o’clock Tuesday morning, Lancaster Police say an officer spotted a 16-year-old behind the wheel with a 15-year-old girl in passenger seat.

The driver was arrested and charged with unauthorized use of a motor vehicle.

“The interior was completely trashed,” said Cabral.

He found candy wrappers and marijuana.

An audio recording system in the car also caught snippets of singing and conversation during the 15 hours the SUV was gone.

“Quit smoking now!” someone says in the recording.

“I guess they had fun in my car last night,” said Cabral.

The manager at Kwik Kar says the business asks customers to leave their keys in their vehicles to keep business moving quickly.

He told CBS11 this is the first time A car has ever been stolen.

The shop is now changing its policy requiring employees to either take the keys or have a customer hang on to them.
