I've thought about this before and if I were going to this I personally would use the "alcatara" or however it's spelled material that comes in the WRX's & STI's. I have a Sonic Blue SVTF obviously with the blue inserts. If/when I decide to do this, I will use the the "alcatara" material to do all the seats and headliner. I personally think that would look really good.
