I have had a lot of Gbody's over the years but most of them when I was younger and I can't tell how good parts I sent to the scrapyard simply because I did not need them for myself and did not feel the need to hang on to them for a future project or to sell them later when they are no longer available and worth more money.
I guess if I had the extra room back then to store them I might have thought differently but regardless I definitely know better now.
I know what you mean. I've got rid of some parts and even a few cars that I later regretted. Now I try to save everything that I can.
