i had a couple of years ago the same story with a red opel gt in tel aviv.
i went to kfar saba, bni brak and more, i found the owners name , adress family and what not, the priviouse owner( was a cop) that the buyer never changed the titel in the dmv office and thats how i got the the cop
its along long story, i could easlly be an cia agent.....x
thank god i didnt buy\get the car
