Hi!
Sorry for the late response, we were on a short family vacation.
Okay, I see how it looks now. I think the best idea in this case is to use a custom code in the search results page to recognize which search instance are the results coming from. I am not sure if there are any widget plugins or anything else available that makes this possible without coding though.
I would use something like this in the search.php file in the theme directory:
if ( $_GET['p_asid'] == 5 ) {
// The results coming from the car search, put any custom code here
} else {
// The results coming from the motorcycle search or somewhere else, put any custom code here
}
This way you can differenciate between where the results are originating from.
