If you can hold off on buying one until Friday, I can give you a run down on the difference between the Trueno and the NSX. I will have my Trueno in a few hours(UPS tracking is cool!)

As soon as it arives I can do a comparison between it and the NSX and the regular cars. This way you will have some more more info on the pros and cons of the cars in question. As for the Pitworks, I assume it will be the same as the NSX BUt I cant state that as a fact because I dont own a Pitworks yet. I am fairly sure that the Pitworks will be a better quality car than the first Skylines, But I dont know if it is worth the extra cash. The NXS is right at $60 with shipping, Trueno is $55 and the Pitworks is $70. I dont want to force you to buy something, I just want to throw the information out there to help you decide.
