Permalinks and mod_rewrite – how to make query url look like directory

Ok,

So I have a car listings site setup with permalinks enabled as standard and it works fine.

However, there’s almost 70k cars on it so I created a custom search page
where the user selects car make, model, year, price, mileage, colour etc…

I’m wondering if there’s a way to add a rule to the .htaccess file that would convert
https://www.mysite.com/used-cars/?make=renault&model=clio etc
to
https://www.mysite.com/used-cars/renault/clio/

WITHOUT breaking the normal WP permalinks. I just have the permalink structure set to /%postname%/

Any help appreciated.
