My favorites for the looks are the murcielago, the zonda, my 911 turbo, and my gtr.
For the grip it has to be my fully equipped dodge viper srt10. It's so easy to power slide it round any corner. I also like my golf gti, and the murcielago. Come to think of it, my s4 is pretty good too.
For the drag it has to be my Nissan gtr or my chevelle ss.
For drift, I like the viper and my gt500.
For speed I like my corvette c6, the Ford gt, and the Cayman, and my m3 e46.
