Yeah, what kind of skills do you have? An ntc3 or tc4 would do it if you were just starting. And remember, if you are just starting, you dont want the best, because it is a lot harder to learn on.
The cars on your list, except for the G4 are listed in a thread of information that I posted up. There's a couple there that are not on your list. CLICK HERE
My serpent is the best for knocking out George(710baby) in a heat.
sl0eg1n's serpent is the best for hitting ratzo headon in the A-main
