History
I am the original owner. Bought the car brand new December 31, 2004. Never meant to be a daily driver, but rather a garage queen, car show, occasional drag strip cruiser. Modifications and upgrades have been slow, but meaningful.
If you have any questions or want to know more about my car and what is done to it, feel free to send me a message or comment and I will be happy to elaborate. The forum is full of good information and plenty of it is available by searching. That said, I will help anyone that needs it or just has questions.
