I thought maybe the parts taken off of the converted cars are being used on some of the "NEW" ones as the windshields must be very rare. My most interesting GT40 sighting was seeing the spyder in the picture driving around the streets of Kirkland Wa back in 2010. There were Mk I, II, III, and 4's at GT40 show being held there. Only the second real 40 I've seen on the street. I saw a silver 40 on the streets of Covina Ca back in the late 60's.
