Like nyc dude said, it's all about allocation and is dealer-dependent. Example, my dealer was allocated two E93 verts that none of their customer's wanted, so they traded it with another dealer who had customers that wanted verts for an E92 coupe and E90 sedan allocation. Problem solved. Perhaps your dealer can do the same for you.
