I'm for preserving the unrestored ones, but if the car is way too gone to be preserved then I think it should be done with all the original pieces it came with, period. Locating original parts is very time consuming but is very satisfying for me. It's all part of the fun of the hunt. Believe me there are some disappointments as well but still I still keep looking. My car is still drivable as is even with the wrong parts. My oldest son is gettin this car and as long as I have had it he is getting a really good appreciation of what this car is and what it means, at least to me. I believe he will be a good 'care giver' for my Z when the time actually comes. I'm thinking it's almost time for me to add his name to the title as in 'and/or' next to me and my wife. That way when I'm gone they both can fight over it.
