Owned a 3.1L 2000 Malibu that I bought in 06 for 5k with 52k on odometer that I used as a daily driver, Owned my present car, an 06 Grand Prix (bought in 09), at the same time. Put nearly 300k on the Malibu and sold it for 450.00 in 2015. Under body was rusted out and had multiple electrical issues, but the tranny and engine were still in excellent shape. I was still getting 33 mpg hwy when sold. It had the infamous intake manifold leak from the start, but I never fixed it since it was an external leak with only a little coolant seepage, and it never got worse. The Malibu never had any major issues. Never needed to change the wheel bearings, calipers, O2 sensors, struts, engine mounts, or other major components - just did brake pads, oil changes, plugs and wires. I would consider buying another Malibu or Buick, especially if cheap and in fairly good shape.
