Now you have,

http://site.com/cars/show/sports --> will list all cars on sports category.
http://site.com/cars/show/sports/5 --> will get the car with id 5 in the sports category.[/quote]

Actually I think your not understanding my full scenario, however your example should help me make it clearer. What if in your example, I want site.com/cars to show the list of all cars, and site.com/cars/sports to show list of all sports cars ? is this not possible without having the method 'show' in there?

I do not want to have to do http://site.com/cars/show/sports. That extra show path seems uneccessary to me.
