Just for reference, I leave my cars stock. My Limited was stock, my C55 was stock, and if I get an SRT-6 it will be left stock. I just prefer cars that way and makes me worry less (did I already say I am OCD about my cars - who isn't though!?) about reliability and such. I agree that while the "napa leather" in the C55 was nice, those Alcantara seats look comfy!
