A nail-biting video shows a car salesman clinging onto the bonnet of a BMW as a thief speeds out of his dealership and onto the highway at 63mph.
Moe Al Kaissey, 23, desperately clutched a windscreen wiper for more than 1km as the driver ran red lights and swerved into oncoming traffic through a Canadian city last Wednesday.
The smartly dressed thief arrived at the dealership in London, Ontario with an accomplice posing as an interested customer looking at a black 2018 BMW M4 worth £41,000.
Moe kept the keys but turned the engine on to show how the vehicle ran before stepping out when the man asked to "make a phone call".
The salesman was standing in front of the car when the bandit floored the accelerator and ploughed right into him.
He held on despite the driver attempting to ram him into a street pole in a bid to lose him, and finally tumbled off on a busy highway.
Moe staggered to the curb, narrowly escaping the path of the accomplice's silver Audi as the pair made off.
He told local CHCH News: "My instinct was just to hang on.
"I was screaming for them to stop. Screaming for other cars to call 911, for somebody to just do something."
Shocking footage captures the masked thief striking up conversation with Moe moments before making his getaway.

Moe's brother Mustafa said: "He was swerving right and left aggressively to try to throw Moe off the vehicle."
When the BMW slowed in traffic, Moe decided it was chance to let go and thankfully escaped with only a minor knee injury and bruises.
The dealership said in a post on Facebook : "We are thankful for our sales rep to be alive.
"The more people that see this, the higher the chances of identifying these criminals and stopping them from doing more harm to anyone in the future."
Police are hunting the two thieves who targeted the Sport Motors dealership and encouraging anyone with information to come forward.
The car's GPS revealed it was driven two hours to North York, near Toronto, but from there the tracker went dead.
