2015 Chevrolet Impala LTZ Package (V6) $16,990

The 1LT adds 18-inch alloy wheels, heated side mirrors, dual-zone automatic climate control, a leather-wrapped steering wheel and shift knob, and the MyLink infotainment system with an 8-inch touchscreen, voice controls, Bluetooth audio connectivity, two additional USB ports (for a total of three), an SD card slot, HD radio, Internet radio smartphone app compatibility and voice-to-text messaging capability for certain smartphones. The 2LT is similarly equipped, but substitutes the V6 engine for the 1LT's four-cylinder. Options on the LT are mainly grouped into packages. The Convenience package includes rear parking sensors, a rearview camera, remote ignition and an auto-dimming rearview mirror with a universal garage door opener. The Advanced Safety package adds a forward collision warning system, a lane-departure warning system, rear cross-traffic alert and blind-spot monitoring. The Premium Seating package contributes synthetic suede upholstery, heated front seats and an eight-way power front passenger seat. There's also a Premium Audio and Sport Wheels package, which includes 19-inch wheels, a rear spoiler, ambient interior lighting, a 120-volt power outlet and an 11-speaker Bose sound system. Finally, the Navigation package adds navigation to MyLink and also includes keyless ignition and entry. A sunroof is a stand-alone option for the Impala LT. The LTZ starts with the 1LTZ sub-trim, which is essentially a fully optioned 1LT plus leather upholstery, but minus the rear spoiler, sunroof, auto-dimming rearview mirror, 120-volt power outlet and Bose stereo. It's also eligible for a couple of options packages of its own. The Comfort and Convenience package adds exterior ambient lighting, the auto-dimming rearview mirror, ventilated front seats, a heated power tilt-and-telescoping steering wheel and driver memory settings. The Premium Audio package throws in the Bose system and 120-volt outlet.
