Which vehicle?

[200sx]

Since I now know the single class restriction has been lifted, I would like to race another class on top of mini. I have quite a large stable of cars, both nitro and electric. For obvious reasons I will go electric but which of the these vehicles would be most appropriate for racing (I've left out the useless ones e.g. Midnight Pumpkin, Baja Champ lol) and what class would it be put in?

Traxxas Stampede VXL
Ansmann Mad Rat
Tamiya Blitzer Beetle
Associated RC10b2

Or should i just go out and buy a Team C TC02C or equivalent?
