In process of buying an 82 GN with a 4.1 that may or may not run.Needs paint and interior work but a near perfect body. Am also "blessed" with an 87 GN that has terminal frame/floor rot but a strong motor and usable interior. Given that only 200 and something were produced, should I retso the car as it was or go frankenstein with the 87 powerplant? Again the 82 is considered a rare bird, but when these do go up for sale they don't seem to get the $$$ that the black cars do.Any thoughts?
