How would I go about creating something like the 'tagging' & 'filtering' that is going on here?

http://www.siteinspire.com/websites?categories=172+73

I have a list of vehicles, which belong to manufacturers, weights, body types, colours, etc, which I'd like the user to filter down the search results, much like the above.

I've tried http://filterrific.clearcove.ca/ but I just can't seem to get it to function properly. There's a few more that I've given a shot but same result.

I assume I could use something like acts_as_taggable_on and do a search through that?

Any help would be appreciated!
