  Horse power and torque is incredible! - 2006 Infiniti M45
  By LeonC626 - February 18 - 12:30 pm

  I originally had my sights on the QX56 but after test driving the M35 and M45, I decided to go with something sporty. The initial test drive with M35 wasnt quite satisfying, so I decided to test out the M45. The V8 on the 45 version has a great compromise on the bulkiness of the sedan. The car takes off like a rocket. The thrill on speed is just one of the best features, the stability is probably the second biggest accomplishment for this car. Body roll is minimal when serving through the lanes in high speed on the freeway. The manual shifting is precise and quick. The only recommendation I have for this car is a six-speed auto gear box insteaf of five and a small lift on the rear facia.

  M45 is IT - 2006 Infiniti M45
  By bsouth808 - September 27 - 4:06 am

  This is the car to own if in the market for something under 60,000. I drove the RL, the BMW 530, and believe it or not the Corvette. Though the Corvette was nice it was not really practicable for the family situation. The power this thing has beats any others in the same bunch. With the Acura everything is standard, but there are no options to get. This thing I have has the DVD player in the roof and on the dash. With rear wheel drive you have no need for SH-AWD. It has a camera for backing up, and trust me if you have never seen this check it out. Intelligent cruise control another thumbs up it really works. Lane changing thingy needs some work. Headlights WOW. POWER POWER POWER

  Best yet - 2006 Infiniti M45
  By WILLIAM B COSTELLO - June 14 - 6:40 pm

  This is my seventh infiniti and the second m45. This one looks and handles much better than my first one. 335 Hp no way this engine puts out a lot more then 335 hp. The voice stuff takes getting used to. The navigation system is the best ive ever used and very easy. My wife liked the car so much she bought a m35x. The fit and finish are perfect

  Best Performance Luxury Sedan - 2006 Infiniti M45
  By shmang - February 22 - 2:40 pm

  This car is simply amazing. With the luxury and performance combined together, few can match. Infiniti gets it just right. It is packed with luxury options to make it a true luxury car, while the 335hp V8 with firm suspension makes the car a true performer. It is not a sports car for sure, which it should not be, as it is a luxury sedan. This car makes the trip enjoyable no matter drive it fast or slow.

  Great Car - 2006 Infiniti M45
  By bob foster - November 12 - 11:00 pm

  The M45 Sport has met my expectations which were high to start with. It is both beautiful and a terrific driving experience. Number one would be the engine and drive train. Best feel of power and control I have ever experienced including BMW540i. It is both design and crafted with excellence and thought. The technology is very good but not quite up to the Acura RL, but I would take the drive train and vehicle design over the technology difference. The features are very extensive and user friendly. One can practically live in the car enjoying all the features and technology. It handles very well at all speeds and conditions as all the reviews showed. I have not been disappointed.

  06 M45 Luxury Muscle Car - 2006 Infiniti M45
  By Silk - October 14 - 4:30 am

  06 M45 non-sport journeyman off lease 32k miles. So much fun to drive you just don’t want to get out. Powerful and smooth acceleration at all speeds. All controls are easy to operate. I’m 6’4 & fit very well in terms of head and leg room. The M45 was the right combination of power, ride quality and technology goodies for me. The Bose sound system is wonderful. The M45 sport was just too stiff a ride for me. The M35 does not have the same power, only 1 MPG difference anyway. I bought the Infiniti extended warranty (bumper to bumper) till 100k miles or 2014. Infinity also has the best car loaner program. You always get a loaner (g35) no matter how old or out of warranty your infiniti.

  Almost heaven - 2006 Infiniti M45
  By MR. B - May 21 - 1:36 am

  You can spend over 80 thousand or less than 30 thousand, this car gives you everything you could desire in every car of every level. The ride, the comfort, the build, the smart intelligent intergration...Nothing was left untouched about the car. For those who desire that name of lexus, and mercedes think again. This is a must have car. I am a owner of a mercedes and lexus and acura, however this car takes the prize. You have to drive it to believe it.

  Awesome Car - 2006 Infiniti M45
  By cre - April 28 - 7:40 am

  After owning several Infinitis over the years, this is by far the best one I have ever had. I have only had the car for about a week, but I can tell that I am going to enjoy driving this car for the next few years. It has many wonderful features and options. The car is very quick and handles great. I especially love the Rear-active Steering (4 wheel steering) and the adaptive headlights. I recommend this car to everyone looking at a new Acura, Lexus or BMW!!
