Oh sorry i been erasing and trying again a lot of times and right now i am making tests with only that product. The issue is, for example, that only product, is dodge and chrysler too, because is usefull for sebring and stratus car. But if a customer use the filter, i want him to see, if he select dodge, in the next filter stratus, and if he select chrysler, i would like appear only sebring.
In my first attempt, i set 2 categories: Brand and Model, so its when i first notice that some products are usefull for 2 or three brands and the second filter didnt discriminate like the client wanted to. So, i put the models inside the brands category... and is where i am now, but still in the product i have sebring and stratus in the same product and is the same problem.
Right now im trying with custom fields, but is like the same, because inside the product i have to set it with sebring and stratus so, is the same what ever i try.
I know it must be a way to get this work, because there are other sites that have this working, but im just too dumb i dont know how to do it.
Here is this site, for example:

Thank you so much for your help, i really appreciate it that you are taking the time.
