I just got myself a '99 NB in twilight blue. The car drives well and I'm in love with it.

But the interiors are in pretty bad shape. I was looking at re-doing almost all of it. BUT, I'm a total newbie when it comes to car. This is actually my first car.

I wanted to know what all should I be looking to replace and where can I source the parts? I intend to do all the work on my own.
Cheers!
