2008 Infiniti M45 x

Finished in a sophisticated Platinum Graphite Metallic exterior over a richly appointed Graphite leather interior with wood grain accents, this 2008 INFINITI M45x represents a compelling fusion of V8 performance, intelligent all-wheel-drive capability, and advanced technology. Showing 104,517 miles, this example stands as a well-balanced luxury sport sedan engineered to deliver confident performance in a wide range of driving conditions while maintaining the refinement expected from INFINITI’s flagship midsize offering of the era.

At the core of the M45x is INFINITI’s proven 4.5-liter V8, producing 325 horsepower and 336 lb-ft of torque, paired to a smooth-shifting five-speed automatic transmission with manual shift control and rev-matched downshifts. What sets the “x” apart is its all-wheel-drive system, which operates with a rear-biased character while maintaining a 50/50 torque split under normal conditions and the ability to send power where it’s needed most. The result is a sedan that delivers both strong, effortless acceleration and enhanced confidence across varying road conditions—an ideal combination for drivers who demand both performance and year-round usability.

The 2008 model year brought meaningful advancements that elevated the M45 even further, including updated exterior styling, a refreshed interior layout, and significant upgrades in technology. This particular example is equipped with the $3,350 Technology Package, which introduces a Bose 2-channel 8-speaker audio system, a hard drive-based navigation system, and a vibrant 8.0-inch color LCD display that serves as the central command hub. Additional highlights include an advanced rearview monitor, voice recognition, an integrated iPod interface, and a substantial 9.3GB Music Box hard drive, allowing you to store and access your personal music library directly from the vehicle.

Building on that foundation, the $2,800 Advanced Technology Package takes the experience even further with a Bose Studio Surround sound system featuring 5.1 digital decoding and 14 speakers, delivering a truly immersive audio environment. A DVD video and audio drive mounted in the center console adds another layer of entertainment capability, while Intelligent Cruise Control with preview braking enhances highway driving by automatically adjusting speed in response to traffic ahead. The inclusion of a lane departure warning system further reinforces the M45x’s forward-thinking engineering, designed to assist the driver in maintaining lane position.

Inside the cabin, the M45x continues to impress with a focus on comfort and driver-centric design. The front power-adjustable seats are both heated and cooled, offering year-round comfort, and are complemented by easy power exit functionality, which automatically adjusts the seat position to facilitate entry and exit. The interior’s wood grain accents add a layer of warmth and sophistication, while the power tilt and telescoping steering wheel allows for a tailored driving position. A power sunroof enhances the overall ambiance, bringing in natural light and further elevating the sense of openness within the cabin.

The driving experience reflects the M45x’s carefully engineered balance between performance and refinement. The V8 delivers smooth, abundant power across the rev range, while the chassis tuning provides composed handling and confident braking performance. This is a sedan that feels equally at home navigating city streets or covering long distances on the highway, all while delivering the unmistakable character of a naturally aspirated V8 luxury sport sedan.

For those seeking a well-equipped, performance-driven luxury sedan with advanced technology, distinctive styling, and the added confidence of all-wheel drive, this 2008 INFINITI M45x presents a highly compelling opportunity.
