Your 79 Newport looks a little nicer than mine Mine is kind of a Chamois color with a vinyl top of the same shade. I got it last summer, it had been sitting for years as it only has 47,000 miles on it. There were no keys or title to be found so I had to change the lock cylinders and apply for a bonded title so I could become the legal owner.
Not sure what was standard or optional on these cars but mine is pretty basic. It has power locks, cruise, tilt, A/C, 318 and a leaky heater core
