PSM - What year did it became optional?

[angman]

I would certainly look for a car that has PSM or TC (traction control). I have a 97 with TC and my buddy had a 2001 without. He lost the rear end on a left hand turn in the dry and totalled his car. I told him to buy a model with the extra safety feature. He now has a 02 with PSM

If you want to know if the car is equiped just look for the top left button. There are three black buttons on the left and three on the right. The non equiped ones do not have the option of turning the TC or PSM off via the button.
