     Cars were selected at random from among 1993 passenger
     car models that were listed in both the Consumer
     Reports issue and the PACE Buying Guide.  Pickup trucks
     and Sport/Utility vehicles were eliminated due to
     incomplete information in the Consumer Reports source.
     Duplicate models (e.g., Dodge Shadow and Plymouth Sun-
     dance) were listed at most once.
