I think alot of people must have ridden Town Cars. Working in Manhattan, nearly all of the car services use them here. They are a dime a dozen around here.
On a side note, one of my friends was given a Town Car by her dad. The first day she had it she parked it on the street in Queens. Next day, she found someone stole her hood. Then the next day someone stole her side mirrors. Everyday she lost some part of her car. There is a huge market for parts for Town Cars here in NYC obviously.
