I had an 80 K5. Great vehicle. Miss it badly, but every lower body panel had rust.
I have a 79 that I got for very little. It apparently sat in a barn for a while. The guy sold it to help with medical bills.
Around the world in miles and looks it with classic GM cancer.
It lives in a building. I need to get a starter for it.
