A man has been treated for shock after being threatened with a knife during a carjacking at a car wash in southwest Sydney.
The assailant is armed, dangerous and still on the run - now behind the wheel of a luxury sports car.
The victim was hosing down his near-new car when the knife-wielding carjacker wearing a "scream" mask grabbed the man's keys and jumped in.
But his getaway was stalled because the thief couldn't figure out how to work the Audi's keyless ignition.
The owner tried to fight back and the pair were locked in a tug of war for several seconds before the car sped off, leaving the owner dazed and in shock.
The carjacking happened at Jim's Mechanics and Carwash in Macquarie Fields on Monday night.
"You know, you don't expect it, you go in to wash your car and you don't expect things like that are going to happen," owner Jim Kalogeropoulos said.
The 52-year-old owner was treated by paramedics for shock and taken to Liverpool Hospital as a precaution.
He told witnesses he'd only bought what he called his "dream car" late last year.
"Personally, myself, I think he was getting followed," Mr Kalogeropoulos said.
"Targeted - they wanted that car, simple."
On Tuesday police were interviewing witnesses as they continue hunting for the Audi with the registration DPJ20N.
