Bob,
You would be missing the speed and all that you love in your car in about 6 weeks. The next 6 years and all the sports will be gone before you know it. I am sure your son will like the racing with you and therefore you would be changing the car back to race in a few years. Leave it the way it is and enjoy when you can. As you know, I have two nice street cars and I have about as much time for them as I do the Dartport. It is a hassle but nothing beats it when we do get out.
