Local Trade, 3.8L Engine, Leather Seats, CD Radio, Power Sunroof, Keyless Entry! From the front and sides, the Impala’s styling bears some resemblance to Chevrolet’s midsize Malibu sedan, but at the rear, the Impala has a more dramatic appearance, where a full-width panel encloses four round taillights. The 3.8 Liter V6 engine is quiet, delivers strong performance from a stand still, and unleashes enthusiastic passing power on the highway. The automatic transmission operates with excellence and produces barely noticeable shifts. The impala is easy to drive and maneuver, and it corners rather nimbly, suffers no stability woes on the highway, and copes well in curves.
