I have a 69 Z/28, with what I believe to be the original drivetrain. I do not have any paperwork with the car, only owner history. Do you think I would benefit enough having Mr. MacNeish inspect the car and write up a certification, or would I be smarter to not to spend that money and just sell the car as it is? I would be looking at probably $2k to have him inspect it, so do you think the market would support spending that to have it done or would I not really add enough value to the car. Any thoughts on this would be appreciated.
