$250 seems to be the standard affair for a 1 day HPDE around here. I know BMWCCA charges about $500 for their 2 day HPDE on weekends.
BTW one thing I find very helpful is to ask one instructor drive your car around the lap (if the driving school allows this). It's both a exhilirating and humble experience, seeing what can be done and how much more I can improve. Also you get a clearer picture (and feel) on where your car needs to be at any point on the track. This is one thing I wish I had done sooner in my previous HPDEs.
needforspeed: corporate track day?!! That must have been a nice event . I'd love to see pics of your M-sport on the track
txusa03: I have an auto. lol, Yeah that Z8 is all over me. That guy's a really good driver and has been doing this for a few years. That Z8 is a total beast though; weighing about the same as the e90 but with a 400hp V8 under the hood..
