[QUOTE=boxsterz] PSM is simply amazing. At speeds below 50mph (parking lot wasn't THAT big) , I could never get the car to spin! I did get it out of shape somewhat, but PSM would dutifully kick in and save me and point the nose in the right direction while simultaneously scrubbing off speed. Many times it did so without my being able to detect the edge or limit of adhesion, especially in the wet. As I honed onto that limit envelope I took off PSM and had some really wild rides. Attempting my impression of Tiff Needell, I easily found myself doing 180's and 360's without much provocation (bald tires) and overcorrected some slides. Saving the first slide too quickly often resulted in me spinning in the opposite direction. It made good learning for fast wheel manipulation, hand over hand steering vs. shuffle steering etc...

Yes, PSM was a definite must have for me. I'm actually surprised by the mixed review so far.
Unlike systems from other car manufacturers, PSM is very unobtrusive in day-to-day driving. For example, the BMW system kicks in all the time and will drive you nuts.
Something to keep in mind, mid-engine cars (the Boxster is my 3rd) have a nasty tendency to get very squirelly after you pass their handling limits. Read BoxsterZ's experiences again. He does a great job of describing how difficult a mid-engine car can be to reign-in when your sideways.
Unless you are a rare driver capable of intuitively staying on the throttle during the chaos & steering out of it -- get PSM.
Then again, if you were this type of driver, you probably wouldn't be asking the question.
