One 1958 Plymouth Sedan v. Pennsylvania, 380 U.S. 693 (1965), was a Supreme Court of the United States case handed down in 1965.

Some police officers followed the suspect vehicle, and pulled over the car because it was "riding low".

The car was seized, and the state also attempted to confiscate the automobile in question as a civil penalty.

The Court ruled unanimously that the Fourth Amendment's protection against unreasonable searches and seizures, held applicable to the states by the Fourteenth Amendment, applies to civil actions by the states as well as criminal ones, noting that one could be subject to an even worse penalty in a civil proceeding, where the value of the items being forfeited might be more than the maximum possible fine in a criminal case.
