I got a Carbonizzare back when the stimulus came out, and while I like cruising around in it, I hated it for racing. Way too easy to spin out, especially with all the demo derby drivers.
Recently decided to try out the Coquette after hearing good things, and fell in love with it immediately. Handles like a dream around corners, and much much better at holding it's line against impacts from other racers, like it just wants to stay facing in the right direction.
Or you can have both like I do, the carbonizzare has a great engine sound, looks great, great performance, fun handling, the croquette looks good too.
