Golf/GTI VI :: Are ESC And Traction Control Deal Breaker?

I am currently researching a new car to get. It will most definitely be a hot hatch of some kind. But there is one problem, the traction control and ESC cannot be disabled on the Mk6 and Mk7 GTi's. This is a huge problem for me because I plan on spending between $20k-$30k and that's a decent chunk of change so I better be having $20k-$30k amounts of fun. It's been well established in other threads that there is no way to disable the ESC without a flash or voiding the warranty (or usually both). I just want to be able to occasionally compete in autocross or handbrake turn around a corner or drift through the snow. Or even more occasionally, I like to put serving trays under the back wheels and lock the handbrake and do a little parking lot drifting. Those things are what makes FWD cars so great, and if I can't do that then I should just get a AWD car or even better a RWD car. I don't want to spend more on a new car to be able to less with it.Most of the contenders allow me to do this. FoST, FiST, Mazdaspeed 3, even the Mini Cooper S will all allow me to do this if I want to but the GTi won't as far as I know. So my question is, Will the ESC kick in and ruin my perfectly executed handbrake turn? Will the car even move if I've locked the rear wheels on serving trays? Will it automatically brake when I try to kick out the back around a snowy bend?This stuff may sound pretty trivial to be deal breakers but I really like VW's and want to get one really bad, but I am not so sure about it when they are so crippled by the nannies and may be forced to look elsewhere. Does ESC/traction control ruin a good time?
