     A surveillance contractor that has previously sold services to the
     U.S. military is advertising a product that it says can locate the
     real-time locations of specific cars in nearly any country on Earth.
     It says it does this by using data collected and sent by the cars
     and
     their components themselves

   Some personal experience: although nowadays cars have electronics that
   can broadcast their location in various ways, additionally the spark
   plugs in the engine emit a wideband signal each time they spark, like
   any other spark does.
