The F30 is nice no doubt but it's a bit awkward from certain angles with certain bumpers/colors. Definitely looks best in Estoril w/ sport bumpers/pkg.
Interior... seems slightly flimsy.. like the door panels/handles seem cheap and plasticky. I like the F30 interior design but E90 materials. I like the E46 design + materials. I also don't like how the F30 uses plenty of stamped steel in its suspension compared to the E90 which uses aluminum extensively throughout. Cost cutting? efficiency/evolution? I don't know.
