Well, that's just it: the Z4 and 5, 6, and 7s are newer models. The 3-series won't get an interior of similar style until it is overhauled, which if I remember correctly is set for MY2006 (I'm sure someone will correct me if I'm wrong). So in short, no, the 3-series dashboard will probably not change much, if at all, for MY2005.
