Has anybody replaced the fabric that is on the roof of the car, and if so with what? Mine is tearing and it looks like crap...

If you could also tell me how much it's gonna run, that'd be great...

 

Yeah, it's a very common fix/repair, on any car. It's called the headliner, it's really just a lightweight foam, with a thin layer of fabric over it. It's glued to the headliner board, which is sort of like a big piece of cardboard molded to the shape of the roof. If you've never done one before, I would suggest taking it somewhere, or having someone help. I'm not sure how much it would run, but I wouldn't expect more than a couple hundred bucks.
