I think what you want is 

    <UL>
    <LI><A href="display_stats.php3?arg=mustang.dat">mustang</A>
    <LI><A href="display_stats.php3?arg=beetle.dat">beetle</A>
    ...
    </UL>

After doing this, your display_stats page can read the argument from
$arg.  Note that you still need to do some checking to make sure people
don't craft a url like "display_stats.php3?arg=/etc/shadow" -- this can
be a security hole if you use the filename directly without checking it
first.
