Saturn had a lot of fit-and-finish issues, but man the S-series was reliable. I had one for 13 years/250,000 miles and barely put more than tires, brakes, and oil into the car.
The oil, though, was interesting. The s-series engine had a design flaw with the oil control piston ring where it would get stuck in its groove due to carbon build-up. The engine would then start burning prodigious amounts of oil — mine burned 1 quart every 500 miles. I put the cheapest oil I could find in as a result and when I did a filter change I’d save the old oil to pour back into the engine (diluted — about 1 qt of old oil and 3 qts of new.). By the time I used up all of the old oil it was time to change filters again.
