Dopper69, you need to drive both, and then decide which is best for your type of driving.
The manual equipped cars just "feel" faster, but in reality they are only a little less than 1/2 sec. faster in the 1/4 mile. Personally I enjoy the 6 spd. over the automatic, but that's my personal preference.
As for handling, the Crossfire can go through a slalom "faster" than a Ford GT (and a few other "REAL" sports cars) and I prefer it over my Viper GTS or my Miata. Again you just need to drive it and decide.
Here in the U.S. it is without a doubt the best "SPORTS CAR" bargain on the market, and one of the most unique designs available.
Don't buy one unless you're prepared to answer a lot of questions, and get lots of looks from everybody you pass.
Good Luck
