<h3>Details</h3>
<p>
Cars were selected at random from among 1993 passenger car models that
were listed in both the <EM>Consumer Reports</EM> issue and the
<EM>PACE Buying Guide</EM>. Pickup trucks and Sport/Utility vehicles were
eliminated due to incomplete information in the <EM>Consumer Reports</EM>
source. Duplicate models (e.g., Dodge Shadow and Plymouth Sundance)
were listed at most once.
