Is the PSM system worth it....

[kk2002s]

I don't have any management systems on my car (other than ABS). I have found that as long as the tires are in good condition, this car is very stable in wet conditions (Different tires will effect wet traction of course). I have only had issues when I drove in a down pour with way over due for replacement front tires. I still remember driving the Blue Ridge parkway for the first time. It was in a rain storm, heavy fog (needed to use the GPS to know when sharp turns were coming up). I was driving way to fast trying to make it from one end to the other in 1 day. I went into some of those sharp corners way, way to fast and the car handled it without any slipping. So IMO it doesn't need to be a limiting factor in your selection process.
