I just did a weekend driving school there with the BMW car club in my new 335 GT, which replaced my orange G8 GT. I had a blast, but I would caution anyone who is thinking of doing the open lapping there for a few reasons.
1. Insurance will not cover your car if something happens to it.
2. It is a free-for-all at the open lapping. If you have never done high performance driving before, this the most dangerous way possible to be introduced to it.
3. I highly recommend something like a driving school. Most clubs will let you race with them if you join. There were Subarus, Lotuses, Porsches a Saab and even a Mustang at the BMW event. I think the Porsche club does an event as well. And you can get insurance for driving schools.
As an aside, when driving back, and I may make a separate post about this, I saw an orange G8 GT turning off of 70 at the Central Park exit. Wondering if any forum members know who that is. They had a strange license plate that I could not figure out but it had an S with a U under it on the right side of the plate. Wondering if it could be my old car that had been salvaged and repaired.
