I see, then answering my question, there is probably no more 80's caprices taxis in New York at that point :(, but a friend who traveled to New York in March 2002 says that on the street there were Crown Victoria 1997 and 1996 models and 2000's models, Honda Odyssey 1995 and he found a 90s chevy caprice, he doesn't remember what year the model was but he says he was sure it was a 90s caprice
so maybe that model was still around
but in minory

PD: I have realized that for some reason my post doubled, sorry if that bothers people in any way, my intention was to ask only one time
