I bought the Malibu used with 40,000 miles on it. It was our second Malibu, with the first one totaled in a wreck. We drove the second Malibu to almost 140,000 miles before selling it. Overall, a good car with good gas mileage. We did replace the power steering pump, all of the front pulleys, and alternator during our 100,000 miles of use. At the time we sold it, the head gaskets were needing to be replaced (A $900 expense if done at the Chevy dealership). We would purchase another Malibu.
A lot of interior room and standard equipment for the price. Fun to drive and easy to park. Loved the fact that the back seats folded down to allow for long objects to be carried. Good gas mileage for a v6 engine.
Air conditioning could be improved so that it did not cut off and on by itself. I suspect this was a fuel savings tactic.
