I had the great fortune of touring  Z Mecca last January.  My son and I were given the tour by Jim, and besides the Superbowl, it was the highlight of the trip.  Jim was very gracious and spent close to 3 hours with us.   I saw this thread and just had to add this and to say thanks again Jim. As an aside I just found a 1972 240z with under 10,000 original miles.  Car has sat covered in a storage shed since 1998 and I am in negotiations with owner.  This is an Az car so there is no rust on the body.
