I bought this car in April 2008. I traded in a 2007 Dodge Caliber SXT that was fully loaded with every option under the sun for a plain jane full sized car to accomidate our family of five. The impala is quite comfortable and has a huge trunk. Exterior styling is fairly attractive and the interior is straight forward and easy to operate. I received good factory incentives which is why I purchased the car in the first place. Most of my driving is short in town driving so gas mileage is about 19-24 MPG. The automatic lights and stereo volume are nice features. There are several features I really miss about my old car, but all in all not a bad car for 18K.
Automatic lights. OnStar! Had to use it already. My husband locked the keys in the trunk.
More cup holders (Only has 2 in the front), automatic dimming rearview mirror. Heated side mirrors.
