Really? Lately I've seen more recent vintage non-Vics. Maybe we're in different parts of Chicago (I'm in the Loop). I see a lot of Scions, the occasional Sienna, quite a few Escapes, even a couple Flex, when I see a Panther, more often then not it is a recent vintage Grandma Keys - Ford making the Vic Fleet only seems to have driven smaller outfits to it.
I do believe NY requires the vehicles to be new.
