  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!!

  gorgeous car, awesome power - 2006 Infiniti M45
  By abeh - April 25 - 6:20 am

  I test drove the Mercedes, BMW, Volvo, Audi, Cadillac, and finally the Infinity M45. Originally I wasnt planning on going to Infinity because I wasnt impressed with them from the outside. When the salesman brought out the new 06 M45 V8 Sport I was in love. Its sleek, stylish, and the interior leaves nothing to be desired. Its fun to drive, and as I live in the mountains, it handles curves and hills like a dream. The bose surround sound cant be touched by any of the other cars out there, and the bourbon and black leather interior is turning heads everywhere I go. Everyone wants to know what kind of car it is.

  M45 Sport - 2006 Infiniti M45
  By AKANORM - March 28 - 3:40 am

  Leased the car mainly becuase I dont think the resale value is there. I looked at the BMW 540i and almost purchase one, but the price difference between the M45 and the BMW 540 was too significant and could not justify it to myself. Im glad I got the M45, I think the M45 is the best value out there. Its has more power then the Lexus 430 (previously owned). Its a nice car and a great value.

  Great Sport Sedan!!! - 2006 Infiniti M45
  By Bobby - March 7 - 9:10 pm

  The 2006 M-45 Sport is a great sport sedan and I think it is the best value of all the good sedans out there. If you compare it to its real peer group, BMW 545/550,MB E500/550,AUDI S-6, it is as fast or faster, handles and brakes better, has more user features in the interior, and is less expensive! My car is loaded with Voice-activated Navigation ,Bluetooth , heated and cooled seats,DVD,6-disc CD changer, leather, 19 in. brushed aluminum sport wheels, etc. It is the best drivers sport sedan I have ever owned. The acceleration is very quick (0-60 in 5.2 sec.), the brakes are phenomenal, and the handling is very flat around fast corners.

  Move Over Lexus! - 2006 Infiniti M45
  By Bill Little - January 14 - 6:00 am

  Having driven luxury vehicles for the past 12 years, I can truthfully say that my Infiniti M45 is the finest auto I have ever owned. Its just flat fun to drive, it has awesome power, particularly low end power, enough gadgets to satisfy even the most demanding technocrat, and styling that equals any vehicle in its class. No wonder its rated so high. Its got my vote.

  Better Buy One...Its "HOT" and "Fast" - 2006 Infiniti M45
  By sho3000cc - December 11 - 3:13 pm

  The M45 is almost perfect for me. I like the whole package with the exception of only a few things!!! It handles like a 2door sports-coupe and roomy enough for 5. This car out-runs most sports-cars!!!! Lifes too short, so buy one now!!!! My lexus gs400 seats , fits me somewhat better but the M45s seats, has more lateral support. They should put Michelin a/s Pilot sports on this car. That would give a 10 out of 10 ride quality instead of a 9 out of 10. Youll also be able to drive it in the snow !

  Great car--low gas mileage - 2006 Infiniti M45
  By SteveB - November 9 - 5:36 pm

  The Infiniti M45 handles like a sports car. It has cutting edge electronics-- the best navigation system available, laser cruise control, keyless ignition, rear camera, an audible warning if you get too close to the white line. Based on my experience, reliability is excellent. The only negative: 15-16 mpg. Since I drive about 8000 miles a year, the low milage doesnt cost me very much. To me, its worth it to have such a high performing, comfortable and technologically advanced car.

  M45 Hi- Tech Executive Jet! - 2006 Infiniti M45
  By Cammer - August 18 - 8:53 pm

  I have to say that I still have the same grin on my face as the day I bought the car. I have never driven a sedan that handles this well. I like to drive aggressively on mountain roads and the M is willing partner. Passengers are blown away by the technology, GPS, bluetooth, self adjusting cruise, lane departure warning I could go on and on. I have yet to have any problems with the car, just oil change. Did I mention the Bose 14 speaker sound! This car is tight! 12 hour drives are piece of cake!

  M45 Sport - The True Positive & Negative - 2006 Infiniti M45
  By Dale Fredrick - July 4 - 9:43 am

  Positives: 335 HP V-8 engine is superior to all others, very smooth & powerful. Seats are very comfortable for long drives,ventilated,lumbar. Voice commands,Bluetooth,NAV,Bose Studio 14 spkr DVD audio & technology features superior. Reliable electronics (Japan),100% Japan parts content & assembly. Awesome tech & features for price point. Negatives: Headliner "clicks",intermittent rattles,road feel & handling feedback compared to new BMW 5 Series is poor,wheel balance on front right was way off. Quirky steering wheel movement on freeways requires continuous tiny hand inputs probably due to 19" tires and sport suspension setup(too tight)After 3000 mi.& 3 months sold car to CARMAX for $48,000.
