Chris. How about a out of the box idea.? Find a used Mazda Miata race car and start going to track days with it. I bet if you take the time to find a good deal you can run the car for a couple of years and sell it for nearly no loss. This will get you some track time, experience with track car maintenance, and a host of new friends involved in the sport. In the meantime, you can continue to work on your plan for a much higher-performance car—just a thought.
