SAN DIEGO (KGTV) - A Tesla owner got a road-rage surprise after a quick shopping trip at a Best Buy store in Carmel Mountain Ranch.

Cory Janney bought his 2018 Model 3 in December. On Saturday, just past 1 p.m., he and his wife drove through the entrance of The Courtyard shopping center.

"As we were coming in, a car drove straight through a stop sign. I honked my horn for a millisecond," said Janney.

The gray BMW drove off while Janney and his wife parked and went into Best Buy. After about six minutes, they came back to the car.

"We were both pretty shocked," said Janney.

Along the front door on the passenger side was a deep scratch. A look at their dashcam video revealed the culprit. Soon after they parked and went inside, a gray BMW pulls into the parking spot next to their Tesla. A man with a green shirt gets out and looks around. In his hand is something sharp, like a key.

"He had stiff arm and proceeded to scratch the passenger side of the door, before getting back into the vehicle," said Janney.

The "scratch" deep went all the way through, past the clear coat and the paint. Janney hasn't got an estimate yet, but one expert told 10news it could run upwards of several thousand dollars.

"It's disturbing something so small could lead to so much rage. If he gets this frustrated, who knows if he's going to escalate it to something bigger," said Janney.
