Two men used a stun gun to steal an Audi Q3 from Hurstville on Friday morning after responding to the owner's For Sale advertisement on a website.
A man, 26, met the two men at his house on Neirbo Avenue about 10am and they asked to test drive the car.
All three went for a drive around Hurstville but as they returned to the owner's home, one of the men pulled out a stun gun and gave him a shock.
He got out of the Audi and the two men drove away. The car was last seen on Woniora Road turning right onto King Georges Road, Hurstville.
Hurstville police want to speak with two men. The first man is described as being of Asian appearance, with a fair complexion, aged in his early 20s, of slim build and about 175cm tall. He was wearing a white shirt, red tie, black pants and black shoes.
