Everytime I ask about suggestions for upgrading my car I get told that the first thing I should upgrade if the driver!! Great, I'd love to; however, I've got a 3.0i Z3. No BMW convertibles in BMW driving schools!??! My other vehicles are a GMC pickup truck and Honda Odyssey - neither of which would be much on a track - so driving one of my other cars is not an option.

Any suggestions?? Rent a car at the track, doubling up with another club member, other driving schools that do allow convertibles. I'm not looking to race, I just want learn how to be a safer driver and get more out of my Z3.
