Have two 1970 z50, seen a lot of people restoring them but are my two better just left alone, cleaned up and enjoyed or are they worth that much more restored. They are not perfect but nice, some spray can work on the blue one. I'm going to clean them up and play i think. More original the better Right? They were both bought at the same time from the dealer in 1970, VIN # Z50A27 And Z50A28 is this consecutive serial numbering. thanks G II
