We have been waiting for a sporty and roomy sedan like the '08 Malibu. Just purchased recently and we are very pleased so far. It has the largest rear legroom we have seen so far in it's class. Even more than the Impala due to the way the front seats are constructed with an indentation in the back of the seat. Very quiet interior. We went with the 4cyl instead of the 6, but it has a surprising amount of power. Excellent trunk space and if you do need more room there is a 60/40 fold down rear seat. Vehicle handling is decent and it is a relatively smooth ride. The new interior and exterior styling is what stands out for me. Chevy did a great job with that.
Auto headlamps, interior lighting, exterior design and body, front and rear legroom, XM, OnStar, info display on dash with oil life, outside air temperature, mpg, tire pressure and other info. Power driver seat, many large cupholders and storage compartments.
These are just suggestions...no real complaints: fuel tank release inside car, Sirius radio, longer trial of Onstar service, GPS navigation display, higher quality wheels on LS model.
