Let me tell you from experience, the girls MAY like the look of convertibles going down the street, but they're really not endeared to cars like guys are; and the first thing they ALWAYS say is "Can we put the top up? My hair's getting messed up."
Quoted for truth. I just sold my BMW 328 convertible because my female could not stand the top being down.
I would go for an S2000 if I had the coin, I do not consider them too girly.
