I would add that I think it's a far better bet to get some tuition on track on or an airfield as I don't think you can learn to drift or slide the rear end around without learning how to balance throttle and steering inputs.
I think that even using hte sport mode, it doesn't allow much slip and though I guess one could learn a little about steering input, the system won't let you modulate the throttle as it does it for you.
I think stability control is more to stop the masses going into hedge backwards, but I guess we should be thankful that in some ways it does allow manufacturers to still produce fun handling cars (once the nannying bad aids are off of course).
