My Z-28 I bought new in 73 and did a lot of modifications to it in the 70s but have ended up with it restored back to near stock as being the best balance for driveability. I worked my ass off in the 80-90s and in this century have mostly been unable to do anything on a regular basis due to health problems. I bought my 50 Packard 3 years ago as is and have done minor upgrades and replacement of starter, carb- easy stuff.
