So roofs, doors, trunk lids, taillights, most of the unibody, etc. are all produced in a much larger volume than the equivalent E92 parts. I don't think the carbon roof is the reason the base prices are so much higher, even though the moonroof is a no-cost option on the E92. The non-M E90/E92 have about the same price difference.

If you look at the 2008 production volume, the sedan production is about 2.5times the couple production. The economies of scale do apply of course but the marketing and perceived market value play a bigger role is pricing of cars. Coupes are "sportier" and command a greater value than "family" sedans.
2008 Production numbers:
2008 total 474208
e90 246231
e91 93191
e92 79248
e93 55538
sedans: 339422 72%
coupes: 134786 28%
