Gables purchased used Mercedes from a German company. The cars were built for the German market and met its safety and pollution requirements. Gables hoped to sell the cars in the U.S., and so shipped them to New York. Upon reaching Customs, the cars will:

A) not be passed through Customs because Germany does not have most favored nation status with the U.S.
B) be passed through Customs because they are not products that would affect U.S. national security
C) not be allowed to pass because they are a major source of competition for U.S. automakers
D) not pass through Customs unless they meet all safety and pollution control for cars operated in the U.S.
E) not be allowed because they are not new cars
