Can an eigth grader distinguish between a ZHP and non-ZHP? That is the question in this thread. We all love the handling on our cars, etc...but having the ZHP is pretty much like the placebo effect. I'm not saying that that the 10HP isnt there, or the suspenion isnt better, only that its nice to know that you are driving the faster 330. But really, folks, you driving to and from work!
