Dart loses it ..

A driver in Stony Plain, Alta., has revealed an apparent weakness with a 'muscle car' — a back axle that completely fell off.

The dramatic break down happened in the town west of Edmonton earlier this month and was captured on a dashcam video that has since been posted online.

The video shows what appears to be a vintage red Dodge Dart passing the vehicle with the dashcam. The car speeds up, wobbles, then heaves back and forth in the far right lane before bouncing, tipping up onto its front end and losing the entire back axle.

Bart VanRootselaar, owner of The Iron Garage in Stony Plain which specializes in vintage and muscle cars, says he cringes every time he watches the video.

"Actually I drove by it that night that it happened," he said. "I didn't see it happen, but I did see it on the side of the road."

He believes the car is worth more than $50,000 and the amount of the damage significant.

The driver of the Dart is not talking, but the tow company that moved the car told CBC the driver had only owned it for several hours before the mishap.
