Got it for high school graduation with 74,000 miles on it and couldn't be happier. I don't know what the previous owner replaced, but I have spent only 200 dollars replacing oxygen sensors. The Stratus is unusually peppy for its price and size while it gets 30 MPG on the highway. To many of the complaint reviews here: The longevity of the car can reflect the way you drive it. The back right window no longer works. Complaining about gas mileage? This gets 21 MPG city, which isn't good or bad, but keep in mind - you are reviewing it in 2004 or so, compare to cars of the same year, technology progresses! I have to admit, the gauges look cool at night.
Gauges, cheap, good gas mileage, if you are nice to it, it will be nice to you.
Anything could improve, this depends on the way one drives. I personally don't care about cabin noise, that's why you have a radio!
