Hello from McKinney, TX. I'm building a Mark 3.1 I started in late 2009. I'm about half way done, it sitting on it's own four feet! I've got a poorly maintained blog at http://dtcobra.blogspot.com, feel free to check it out.
Outside of the wife and kids, this is by far the funnest thing I've done in my life. Every moment in the garage is priceless!
Daniel
