Where in New York City can I buy a 12 volt fridge for in car use ?

You can buy them online from Amazon of from a Sears store Sears: Online department store featuring appliances, tools, fitness equipment and more (http://www.sears.com/shc/s/p_10153_12605_SPM201474968P?sid=IDx20101019x00001a&ci_src=14110944&ci_sku=SPM201474968)

Try Paragon sporting goods or Modells. Target used to carry them too. Also try Strauss Auto Stores.
