So, I've been thinking about taking an "Advanced" Driving school for a while. I would love to better my driving skills in a way that I could use in my everyday. This actually started when I thought about signing up for one of those "Exotics Racing" events, but then realized I think it would be cooler to have better driving skills than take a Ferrari around a track (with no idea how to control it). I put this in the Off-Topic, as I wanted to see if people had suggestions for what I'm looking for. I'm in Southern California, so it should be easy to find something. Also, my BMW is on lease, so I don't know if that limits what I can/can't do. I would love to learn in my own car, but I can see the dealership not being too happy with that. Thanks for the help!
