Have you ever had the chance to drive a real muscle car?

Neither an NSX or a Skyline were designed to be the best straight line racers. For one, the skyline is AWD (at least when it's not a family sedan), and the NSX has a no-balls motor. h:

That is not why people buy them. And if somebody does buy a Skyline to drag, they don't do it stock unless they just want to see what they can do before modding it. (read, RWD conversion)
