        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.
