The Infiniti M45 was introduced to the car-buying public in 2003, and the 2008 Infiniti M45 offers consumers several upgrades. The one that created the most buzz was the addition of the ATTESA E-TS all-wheel drive system to the 4.5L, V8 version of the M45. If you are considering the Acura RL, Audi A6, Lexus GS, Jaguar S-Type, or one of the Mercedes-Benz E-Class models, you may also want to add the M45 to the mix.

This model comes equipped with a 325 hp, 32 valve V8 engine, a five-speed automatic transmission (manual shift mode), and either 18 or 19-inch aluminum alloy wheels (depending on whether you choose the Sport model or not). The M45 gets an impressive 28 miles per gallon on the highway and 19 miles per gallon when driving in the city.

For 2008, the Infiniti's interior and exterior were improved to give the occupants a very comfortable ride. From the leather bolstered front seats with exotic wood or alloy accents (available on the Sport model), this luxury sedan says, "Class." It seats five people comfortably, and cup holders are provided for front and rear seat occupants of the vehicle.

The Infiniti's features include dual-zone automatic temperature control feature. Buyers will appreciate the power glass sunroof when the weather is fair. The M45 comes equipped with an AM/FM radio and six-disc CD auto changer; MP3 and WMA playback is available.

Car buyers interested in the M45 can also add the Premium Package (optional). Adding this to your ride means that your passengers will be able to take advantage of reclining rear seats (heated!), HVAC, and a power rear sunshade.

If you choose the Technology package for your M45, you will get Bose Studio Surround, a DVD navigation system that comes equipped with an LCD screen (eight inch), and either XM or Sirius Satellite Radio. The Lane Departure Warning is also offered with the Technology package.

Some great safety features are standard with the M45. Not only does this model have front impact airbags, but it also comes equipped with side impact airbags (seat mounted). In addition, the 2008 Infiniti has first and second row overhead airbags.

With the 2008 Infiniti M45, you get a vehicle that looks beautiful, is comfortable, and gives you good gas mileage to boot. At an MSRP of $50,250, you are getting what you pay for.
