Tom, did you say you tried the Infinity G37? I'm too lazy to look. If not, the G37 has a "Sport" option in either sedan or coupe or convertible. The sport version comes with a manual six speed, 320 plus HP and some pretty slick wheels / tires. The convertible is actually a retractable hard top, which might just be the thing you need where you live. I have not driven one, but Infinity has always impressed me overall. New, they're about 35K, so you should be able to find one a year or two old in your price range with warranty. Just another thought....
