<if condition="$car != ''">
<if condition="$roof == 'black'">
<if condition="$paint == 'red'">
<a href="#">redblack</a>
<else />
<if condition="$paint == 'blue'">
<a href="#">blueblack</a>
</if>
</if>

and so on....


what might be easier for you though is to make buttons with the specific color.
so if you want an image to show for the blue-red car, name this image bluered.gif
and call it up with $userinfo[field5]$userinfo[field6].gif
That should work...
just make a check for if there's no data entered.
