Ben,
I have driven the north course at AutobahnCC a few times and I must say it rocks! I have driven once on a club track day, usual stuff. Other times I was allowed on as a guest of a CC member. On one Wednesday I loaded up got to the track around 11:00am and was on the track with only 2-4 cars all day long!
The buy-in is $25K which you can re-sell for whatever the going rate is in the future, but only retain 30% of the proceeds. There is a $4000 yearly dues also. This buys you full access on member days (4-6 days a week) from 8:00 am til dark when they shut down for the day. This includes corner workers and a saftey crew.
I think it is the best idea for us guys not skilled enough to race competitively or drive our cars that don't fit a classification that is realistic. Driving schools can teach you the principles but nothing but seat time can make it stick.
I know what I am asking Santa for!
