I'll jump in and add my 2cents worth .... I just read through the entire thread, and I think that something has not been stated here. If I remember correctly, one of the factory representatives was discussing the difference between the Performance 85 and Standard 85 packages. He stated that one would most notice the difference between the standard and performance versions in the under 60 mph times. Above that, when it comes to overtaking and passing, he said both were almost identical - to where one would not notice the difference. With the extra torque the performance car has, it will be most noticed when changing the mass of the car (4600+ lbs) from stationary to moving as is evident in the different 0 - 60 times. I drive a BMW M car - with acceleration in the mid 4 second range on 0 - 60. It can almost be scary fast, and I vary rarely use that balls-to-the-wall (sorry ladies) acceleration, but do enjoy the quickness of the car. I think that in real-world driving, the sub 6 second 0 - 60 times of the Standard 85K packatge will be way more than adequate, and if both cars have essentially the same overtaking capabilities in the 50 - 100 mph range, you have to really think about the extra cash a performance version requires. Having said that, I have priced out both a standard 85K car, and a performance 85K car, and my difference is $8500. There are actually very few full size cars that get a sub 6 second 0 - 60 time, and a very small number that are sub 5 second. I guess that realistically, we all have to ask ourselves if the difference is worth it in "real world"driving.
