This thread is somewhat pointless if no-one is going to give actual reasons for their choices.
Also, 'with supporting mods' is pretty obtuse: If you won't specify, then it's pretty much worthless. You might as well say that the best car is a 350Z with supporting mods. Also, without removing all the superfluous posts (and that includes this one), it becomes incredibly hard to scan (if it's not anyway) to get an idea of what people are using. It's not a terrible idea, but let down in execution and the fact that no-one bothers searching for things as a rule, and the thread title is hardly conducive to helping that.
Yeah yeah, I know that's a really negative post and I'm sorry, but it's the truth.
