There are three trim levels: base, LS and LT. Base models come standard with a 40/20/40 split bench seat, air conditioning, a tilt steering wheel, 17-function driver message center and deep tinted glass. Mid-grade LS models add power windows and door locks, remote keyless entry, an AM/FM/CD stereo, cruise control and a leather-wrapped steering wheel. Top-of-the-line LTs come with power heated leather seats, the OnStar communications system, a self-dimming rear view mirror with a built in compass and power heated exterior mirrors.
