^^^+1 on what Joe said. My dad's told me the same thing when I've asked him about his.
He's owned his 1997 Malibu Sunsetter since 1996, he said its usually a couple hundred a year in maintenance, (nothing major), and the most money it's cost him in nearly 15 years is a new transmission,which he said was around $1000 installed. I'd say that's extremely low maintenance, try driving a car for 15 years and get away with that.
