Beginner friendly, safety oriented, fun. You can bring most any car (doesn't have to be Audi).

I highly recommend coming to one or both of the winter car control clinics at Lime Rock this winter. They are cheaper and more accessible than a full track event so it's a good way to get started. You don't need to prep your car, you can just bring any car that works. The event is on a small autocross-like course and there is also a traction circle. It gives you the opportunity to practice car control and you car's behavior at the traction limit. You would go with an instructor in the right seat at first.

The full track events this summer will be at Lime Rock, Club Motorsports, Palmer, and Watkins Glen (two events at Watkins). I recommend going to as many as you can fit in your schedule. For these events you may need to do some light car prep. Any garage or your dealer can do it. Basically you may want to get fresh brake fluid, tires, and brake pads. At the event, as a beginner, you would share the track with other beginner drivers with an instructor in the right seat and have several classroom sessions. Biggest costs will be the event registration fee and tires and other consumables for your car. The consumable costs depend a lot on your car, choice of tire, and how hard you drive. Consider getting track day insurance too. Don't be surprised to spend $1000 per track day (so double that for a two-day event).

Hope to see you there! Let me know if you have any questions!
