  Im in Love with This Car - 2003 Infiniti M45
  By Natalie28 - April 7 - 2:00 am

  Incredible vehicle...designed for a man in this late 40s. Im a women in my early 30s and think this car is the most beautiful Ive seen in a long time. It would have cost me 10K more for an underpowered Mercedes. Yah, that made sense.

  Way Cool - 2003 Infiniti M45
  By Alan Acosta - February 13 - 10:00 am

  I moved from a BMW 330 coupe to the M45. I enjoyed the BMW, the M blows it away for just a few thousand more. The BMW was more sporty, felt the road more, yes. all thats true. But given all those people in their automatic 325 sedans, I think that argument is hooey. The M drives really well and knocks you back in your seat when you take off. Build and fit-finish are excellent, gadgets fun. Finally, the M has taken its knocks for its "look," --too conservative, too chunky, whatever--but I have gotten rave reviews from friends and people on the street. Lots of power and bang for buck--this car rocks.

  A Real Sleeper - 2003 Infiniti M45
  By troxl - February 7 - 10:00 am

  You dont see this one coming. It has class, features, and a 340 horsepower V8. This car outclasses my Bonneville SSEi.

  World Class - 2003 Infiniti M45
  By hofame - January 7 - 2:00 am

  Safety, Power,sure footed responsiveness, Cost, Technology with a dash of analog ... make the M 45 a World Class vehicle. A must test drive for those that are in the market for a quality vehicle. Toyota, Lexus, Mercedes, Volvo take a back seat for similar vehicles in the same price range.

  MIND BLOWING SPEED! - 2003 Infiniti M45
  By gray_M45 - January 7 - 2:00 am

  My wife and I we about to buy another BMW 745i when we saw this car at the car show. I bought one the next morning after driving it. And I saved about $40K. I cannot believe the power, handling, technology, comfort and refinement of this car. Lets not for get the price, mine is loaded and it is still under $50K. I get more comments on my M than my wife gets on her brand new $82K BMW, and I can beat her car any time any place. Needless to say she cannot wait to get one.

  Powerful Sport Sedan - 2003 Infiniti M45
  By qualityfirst1 - November 30 - 9:13 pm

  This car intrigues you. A true Jekyll and Hyde. Lots of power - Manual mode on transmission is worthless. Comfortable seats - Hard to reach seat controls. Nice wood and leather interior - console and glove box are loose. Lots of goodies - Too many steps involved to enjoy them. Feels great up to 120 mph - feels unsafe at 125 mph. Big car - Interior feels narrow. I like the handling and performance of my car, but it does not have give you feedback like my BMW 540i. This car is a sleeper. You can pull away from nearly every car on the road. Stereo system is very nice. Ours is black with tinted windows and chrome wheels - I think the best color for this car. Engine burns lots of oil!

  Really is the Muscle Car with Brains!! - 2003 Infiniti M45
  By Daren - November 30 - 2:00 am

  Ive had my M45 for about a month now and it is so much fun to drive, yet sophisticated too. It ourpowers my old Jaguar S-Type 4.0 and has all the interior features of that luxury car. Please, it makes a really neat growl when you start it and accelerate.

  This babe is an eye-catcher! - 2003 Infiniti M45
  By Kenny M - August 25 - 10:00 am

  Ive put on over 5000 miles on the M in just under 3 months...simply put...its a blast to drive! Got it fully loaded except for chrome wheels (looked too gaudy). Got the windows tinted immediately and let me tell you...this car gets looks!! Havent seen a single one on the road yet...feels like a custom-made car. I almost went with the Mercedes C32 AMG and changed my mind...so glad I did.
