Let's just say I have a way of finding things out.
Is it truly a consensus when it's just people on a message board giving their own personal opinion rather than fact? I think not.
As for a different mold for the sedan, big whoop. Don't you think they planned it out when they developed the new molds for the sedan fenders, hood, front and rear bumpers, and trunk lid? You guys seem to presume that BMW engineers are building the E90 sedan as an afterthought rather than something they were intending all along.
Oh, and what percentage of the coupes being sold in the US will have a moonroof? My bet is that it's going to be more than anyone here thinks and is willing to accept.
