Not a bad choice between the two, but BMW considers the coupes to be their sportier offering. Rear seat in the coupe is usually more comfortable than the sedan (once you get back there) because they are more contoured. Those that think the sedan looks better seem to concentrate on the rear fender profile, but to the designer in me the cleaner greenhouse sides of the coupe with the frameless doors, along with the sleeker roof profile and C pillar seal the deal. I also like the taillights on the coupe better than the sedan's notched ones. How many prefer the sedan based on this comparison?:
