I purchased all of this for my 2011 335i a few years ago from ECS, but ended up selling the car before replacing anything. All of it is brand new, but has been sitting in my garage taking up space for a couple years now. If you bought from ECS right now, it'd cost $561.48 plus shipping. I'll sell it all for $300 shipped to the first PM.
