I have come across two 240z cars. One is 1971 white with 71 miles on it, not 71k just 71. And a 1972 240z with the green rally package with only 138 miles. Both belonged to a dealer who parked them in a garage packed with NOS parts. He has since passed away and I am selling the estate. Any help on value would be appreciated. I have pictures if that helps
