The 2014 Ford Mustang is available as a coupe or convertible, offered in four trim levels: V6, V6 Premium, GT and GT Premium. The Shelby GT500 is reviewed separately and the Boss 302 is no longer available. Base V6 models start with 17-inch alloy wheels, xenon headlights, a limited-slip rear differential, keyless entry, integrated blind-spot mirrors, cruise control, air-conditioning, full power accessories, a tilt-only leather-wrapped steering wheel and a four-speaker sound system with a CD player and auxiliary audio jack. Stepping up to the V6 Premium adds upgraded 17-inch wheels, leather upholstery, a power driver seat, Bluetooth, Ford's Sync voice activation system, an auto-dimming rearview mirror, color-adjustable gauges and ambient lighting, a color information display between the gauges, upgraded interior trim and a premium eight-speaker sound system with satellite radio and an iPod/USB audio interface. The V8-powered GT comes with the base V6's features plus 18-inch alloys, automatic headlights, a rear spoiler and foglamps. The GT Premium is essentially a GT with different 18-inch wheels and the V6 Premium's roster of features. The 2014 Ford Mustang's interior can be appointed with all of the modern conveniences we've come to expect, while also paying homage to its rich history. Sync's voice activation features greatly simplify operation of audio, phone and navigation systems. The buttons themselves don't have a particularly solid feel, though, and a large percentage of the door panels and center console is taken up by hard plastic.
