Looks nice but definitely low option. As a Mass. car, it may or may not have AC. https://southcoast.craigslist.org/ctd/d/berkley-1977-oldsmobile-custom-cruiser/6960549493.html
And it has been repainted as the Custom Cruiser script on the front fenders is not where it should be.
One way or the other, I love that Orange / Brown (woodgrain) / Tan (interior) color scheme on this 77.
For $8400, he needs more photos of the interior, especially of the dash, and any at all of the engine. He also needs to talk more about what options it actually has. From what we can see, it has a remote control driver's mirror and a luggage rack. No power windows, locks, or seats, no cruise control or tilt wheel, no rear window defogger. As jwdtenn notes, low option.
