Here are some pics of my ML with headlining, pillars and visors done by D:Class, following Peter (C43AMG) recommendations. They did a cracking job. My plastic bits were colour coded by a local shop, using plastic paint and matt lacquer. They came out great as well.

On a side note, if you want you can DIY the alcantara in your car. Just buy a material from Dunelm Mills @ £11/sq m, get an Evo Stick glue and some pegs and off you go. I friend of mine did his car himself and it turned out looking no different to mine.
