I'm looking to buy a roof rack system for my 2006 TC, but I know absolutely nothing about what parts are included, what fits the car, etc. I'm just completely unfamiliar with these as I have not even seen or touched one at all yet. I am perfectly ok with buying them used, and getting whatever parts I need that are specific to make it fit my car... I'm just not sure what parts are interchangeable and what parts are specific.

I know alot of people have TC's and a decent number of those have roof racks on them, so any helpful info, or "beginner's guide" as to what I can buy, and what I need to pay attention to, would be greatly appreciated. Thanks.
