BADLT4
FASTLT4
2FAST4U
FASTBLK
12SEC96
IFUDARE
ROCKER
My favorites are: BADLT4, FASTLT4 AND IFUDARE.
The ROCKER one sounds kinda high schoolish.
2FAST4U sounds too rice burner like; maybe because I think 2 Fast 2 Furious.:L
12SEC96 gives them too much information! They should find out that you're a 12 second car.
IFUDARE is my favorite, it's daring and cocky. It's like an open challenge.
