Car-loving comedian Jerry Seinfeld watched in horror as a motorist ploughed into his prized Porsche on Monday (18Aug14).

The funnyman was drinking coffee with a pal on a street bench during a vacation in The Hamptons, New York when a Bmw driver shunted his parked car.

The rare 1973 Porsche 911 Carrera Rsr suffered damage in the incident in Amagansett, and photographs published in the New York Post show the furious funnyman remonstrating with a female motorist.

He tells the newspaper, "I was sitting on a bench, having coffee with a friend. My car was parked directly across the street. We then watched as a middle-aged woman in a new, white Bmw sedan pulled in front of my car, put her car in reverse and drove straight back into my car, smashing and damaging it.

"We could hear the sound of metal crunching - rare, classic, expensive, vintage metal, by the way - from across the street. A sickening sound to a car person. And even though I'm sure I deserved this, because of who I am and that I have this amazing car, I was furious. I ran across the street, out of my mind, and yelled at her, 'You just crashed into my car!'

"Of course, her reply was not, 'Oh, my God, I'm so sorry,' but, 'Well, I couldn't see it.' She didn't seem to understand why I would be upset or how this was in any way her fault. She drove off. She did offer to give me her information, but the idea of having her in my life for one more second was intolerable. I went home and put my head under the covers."
