I have an automotive website that sells all kinds of parts for your vehicle. Using categories is fine but I want something a little better and more of an industry standard. What I need to have is a way to filter results with keywords, like manufactures does. I want to group a bunch of items into 1 group but also have them in another group all done inside the item itself. This way I can have the manufacture as the main categorize making it easy to put all their items on sale and update them and also giving the customer a way to find the product through several variables. I have several manufactures and the parts fit into different categories.

I want it setup just like the music product type where I can have one item go into several filters.

My filters need to be:
Manufactures
Suspension
Drive-train
Performance
Interior
Exterior
