i would definitely go for the coupe. my dilemma is different, however. i can't decide whether to get the regular coupe or the M one. i figured in 4 years (when i'm ready to upgrade/swtich) i'll have this question figured out.
but as ward said, i'd test drive both of them and i'm sure you'll have no problems deciding which one you like better.
