Hi '68 Z28 fans, I know this will be a vague question but I do not want to walk into this clueless. I am on the trail of a '68 Z28 one owner car. I do not know much about the car other than it is Not an RS. It has the born with motor ,trans and 410 diff. Pretty much rust free Ca car, Flat hood gone in place of cowl hood and original carb changed to holley carb. She told me she paid 5400.00 new and her credit union told her she was over paying for it and she told them she wanted it anyway. It was a showroom car, she drove it off the lot. I know showroom cars usually are loaded or flashy in some way but I will know more later. Big question is can someone give me a ballpark on the value. Right now it's just sitting on blocks under a plastic tarp in her backyard.
