I have a Custom Post Type named "Cars" and 2 Custom Taxonomies "Ferrari" and "Lamborghini". Each taxonomy has 2 Terms: "New" and "Used".

The problem is, of course, when I append the car ID at the end I get a 404:
I've been playing a lot with add_rewrite_rule/add_rewrite_tag and read many discussions here on StackExchange but I couldn't find a solution. I also tried WP Router and it actually works, but it almost entirely overrides the default routing so that it feels like a hack.
All I need is being able to route the URI with the appended ID to the same template as it would without, so from there I can make a custom query using the ID segment.
