Talk About first world problems
The 4 Series is a much better looking car in the 2 door guise, but in the 4 door format its not much better looking than the 3 series, I think the issue comes in as our roads are flooded with F30s so the 4 series might be more appealing than the 3.
if I were you id go for the 330d , just a pitty its not alpine white...
