A mechanic for a West Islip car dealership has been disciplined after a dashboard camera caught him driving a customer's car close to 100 mph on Sunrise Highway.

John Gentile, an attorney for Atlantic Chrysler Dodge Jeep Ram, did not disclose the disciplinary action against the dealership's mechanic Tuesday, but said it acted immediately after the customer complained and even made three repairs to the car, a Chrysler 300.

Gentile acknowledged that the mechanic drove at a high rate of speed during a test drive; a 20-minute dash-cam video indicated high speeds of 96 to 97 mph, he said.

"Going at a high rate of speed is a concern to us," Gentile said.

On three separate occasions, after the customer complained, the car's bumper was repaired, as were scratches to the dashboard and exterior of the car, he said.

"All repaired, when nothing on the video showed it was damaged during the test drive," Gentile said.

The customer, Joe Fradella, of Levittown, said that he first noticed bumper damage after taking the car in for a routine service check on July 31.

Then, while clearing out video files on his camera before a family road trip the next day, Fradella found a clip of the service trip and said he "put two and two together."

"I'm getting more and more aggravated as I'm watching it," Fradella, 43, said. "I immediately took the video down to the dealership."

Gentile said that such test drives are common. He said the mechanic stopped at his apartment a few miles from the dealership during the drive.
