The '07 Buick LaCrosse comes in three models. The base CX and the more luxurious CXL are powered by Buick's veteran 3.8-liter overhead-valve V6, rated at 200 horsepower. The performance-oriented CXS comes instead with a 3.6-liter V6 with modern double overhead camshafts and variable valve timing; although slightly smaller in displacement, it develops 240 horsepower.

CX ($22,230) comes with cloth upholstery, manually operated air conditioning, tilt wheel, six-way power driver's seat, programmable power locks with remote keyless entry, power windows and mirrors, theater-style interior light dimming, leather-wrapped shift knob, and a six-speaker AM/FM/CD sound system. All models also come standard with OnStar hardware and a one-year subscription to OnStar service. For '07, a tire-pressure monitor has been added to the standard-equipment list as well.

CXL ($24,645), features leather upholstery, dual-zone automatic climate control, a leather-wrapped tilt-and-telescope steering wheel, power lumbar adjustment for the driver's seat, a split-folding rear bench seat, driver information center, and content theft alarm.

CXS ($26,860) comes with thicker anti-roll bars front and rear, and 17-inch wheels and tires to go with the more powerful V6. CXS also boasts additional touches like driving lights under the front bumper.

Five- or six-passenger seating is available. Front bucket seats with a center console and leather-wrapped floor shifter come standard, but a six-passenger option for the CX and CXL is available that moves the shifter to the steering column and substitutes a 40/20/40-split bench seat whose center cushion flips over to become a mini-console.

A Comfort and Convenience Package ($690) for CX adds a remote vehicle starter, multi-language driver information center, dual-zone automatic air conditioning, a theft-deterrent system, steering wheel-mounted audio controls, tilt and telescope steering column, visor-mounted illuminated vanity mirrors and a cargo net.

A Driver Confidence Package for the CXL ($1,250) and CXS ($1,150) adds steering wheel-mounted audio controls, universal transmitter, electrochromic inside rearview mirror, dual heated and power-operated outside rearview mirrors, six-way power adjustable front passenger seat, Ultrasonic Rear Parking Assist, rear passenger interior reading lamps, and tilt-and-telescoping steering column.

Other options include nine-speaker stereo with MP3 capability ($545) or six-disc CD changer ($695); digital audio with XM Satellite Radio ($199) that includes a one-year subscription; power sunroof ($900); heated front seats, now available with cloth or leather ($295); power adjustable passenger's seat ($350); 17-inch chrome wheels ($650-750); remote starting ($190); and an engine block heater ($50).

Safety features on all 2007 Buick LaCrosse models include anti-lock brakes (ABS), traction control, a tire-pressure monitor, and side-curtain airbags, along with the required front airbags. Optional safety features include park assist and StabiliTrak electronic stability control.
