Factory Five Roadster

Factory Five’s DVD and the very active forums on the car and how to build it really convinced me to move ahead with a Factory Five Roadster.  I placed the order in November 2003.

The Delivery January 2004

Stewart Transport delivered the frame, body and many boxes late one night.  I had already built the body buck so it was ready to receive the body.  The over/under storage scheme that this enables is really great.  Officially this is FFR4870K 2003.
