Keith,
I looked at many of the pics of your car. I am amazed that you had this vision that you were able to make a reality at such a young age! Awesome job! You have a great future in whatever this is that we are all doing here. If you are like most of us, in a few years (or less) you will be designing the next project in your head and working to make it a reality also.
BTW, Persistence beats the crap out of talent any day. Well, most days anyway.
