  Ivory Pearl - 2003 Infiniti M45
  By Ivory Pearl - April 14 - 8:10 pm

  This vehicle is reliable (at 90K miles) and still drives the same as when I drove it brand new off the lot. As an engineer, this car has all the technological gadgets one could want or need. Amazing driving performance (power - 340HP & 333 ft.-lb. of torque and handling) and style. I havent had any issues except a recent gas gauge replacement by the manufacturer. This vehicle is incredible when I compare it to previous vehicles such as: 1991 M3 and Acura 3.0 CL.

  Nice ride - 2003 Infiniti M45
  By Rnewell - March 8 - 2:00 am

  I was surprised to read the knocks on the body style. I added a spoiler and tinted windows and in the first week was stoped and told how nice the car looked. The best part in the performance the car is a rocket on wheels. As a prior BMW 540 owner I think this is just as fun to driver with a much more reasonable price.

  Preety Good - 2003 Infiniti M45
  By robertem1 - December 19 - 10:00 am

  Ive had my M45 4 months, and 5K miles. I took a long trip out west with it and got to work it hard. I got excellent mileage (23-24) at highway speeds. I love the power and can almost get the numbers that the magazines do. It handles very well at triple-digit speeds and is smooth and quiet. I experienced a problem with the tire pressure monitor, but once reset, it worked just fine. The interior looks very classy and elegant. The only things that I dont like are the transmission shifting and lack of bass in the stereo. It is just a shade short on headroom too. I will live with that for the $18 K under the Cadillac I WAS going to get.

  Fun Drive - 2003 Infiniti M45
  By poli27 - December 13 - 10:00 am

  My former daily driver was a BMW 540i. This car is much more comfortable with superior build quality. While it doesnt handle as well as the bimmer, the acceleration and overall performance is impressive. This is our fourth Infiniti (between my wife and I) and a very pleasant choice.

  Whats not to like? - 2003 Infiniti M45
  By barcou - December 9 - 2:13 pm

  Bought a used, loaded, black 2003 M45 and it is as perfect as I think a car can get. Matter of taste of course, but I think it looks great (esp. from rear 3/4 angle). Drive is tight and sporty but not harsh. Feels a lot lighter on its feet than it should -- very planted though. Has that rare car appeal since you dont see very many on the road. The odd stare once in a while. Reliability not an issue, unlike my 325i. All in all, just about perfect. Only gripe is when radar lens cover gets gummed up (I live in Calgary, Alberta), it shuts down cruise control altogether.

  Good fast car. Always in front. - 2003 Infiniti M45
  By Jack Orr - October 31 - 10:00 am

  The car is not as well packaged as the A6-there is less knee room in back and a very skimpy trunk. But, I found the reason for this is that the fuel tank is located between the back seat and the trunk. The safety benefit of this is obvious. The body is not what I would call a leading edge design. The paint job is excellent, everything fits, the doors close well. Fit and finish is top rate. Suspension is very good. Steering quite up to the task. The most outstanding feature, by far, is the engine. Oh, a last thought. The body is very rigid. No groans or squeaks. And it promises to be very reliable.
