Ya, it's really not all that hard. I did it to my 850 because the roof started sagging. I went into the project with no knowledge or expertise on what to do. If I remember correctly, I did NOT need to remove any pillars. Once I got the trim off near the doors and around the sunroof, the head liner just pulled out from behind the pillars. I had to fold it slightly to fit it out one of the door ways. I used the orange 3M spray adhesive with black cloth (backed with foam) from a local craft store. Only took me a few hours and like I said that was with no experience. Came out looking great. The pillars in that car were beige so the contrast was kind of cool.
