Having said that, this is a really nice looking 3.0S.
The 3.0S was an impressive car in its day. (You can find a November, 1973, Road & Track test here.) It was large, fast and luxurious. You can look at it as the grandfather of today's 7 Series.
The 3.0S was a well built car, but it had two very big problems. Cylinder heads on late 70s BMW sixes had a nasty habit of cracking. BMW redesigned the head sometime in 1980, and many cars have been retrofitted with newer heads. The easiest way to prevent an older head from cracking is to buy a more efficient radiator or have the one in the car recored. A lower temperature thermostat is also recommended. Rust was the second problem. These cars rusted in Italian-like fashion. This car, located in NY and having a Vermont oval sticker on the back, should be thoroughly checked for rust and / or poor rust repair. (The seller says it has two rust spots on the "lower drivers side", but they're tough to see in the pictures.)
This car looks to be in really nice shape. The black over red color combination is one of my favorites. Everything looks to be original and stock, right down to the wheel covers.
Many JaCG readers will dismiss this car because of its automatic transmission. That's understandable, but really, at this point in this car's life it's more of a relaxed weekend cruiser than a racer. Put the car in "D" and enjoy the drive. (Or, convert it to a manual - The Senior Six Registry offers a how-to guide.)
