Overview & Reviews

Infiniti has moved the CD changer from the glovebox to the dash. Several of last year's options are standard for 2004, including heated outside mirrors, an auto-dimming rearview mirror with Homelink and compass, two-position memory for the driver seat, a tire-pressure monitoring system and a full-size spare tire. The navigation system (with voice recognition technology) is now available as a stand-alone option.

• Brawny V8 engine, capable handling, plenty of luxury features, reasonable price.

• Limited rear-seat legroom and trunk space, complicated center stack controls.

  What a fun car!! - 2004 Infiniti M45
  By Peter - June 28 - 2:16 pm

  My first car in this class and I wanted something reliable, which meant it had to come from Japan. So the choice with this or a Lexus, and I have no complaints. After having the car for almost two years I still say WOW! Fast, smooth, and great options. It took a little wile to learn how the options work...but after you understand they come second nature.

  Getaway Car - 2004 Infiniti M45
  By kevin 5 - February 27 - 2:00 am

  Car shopping last weekend, drove this with the dealer saleswoamn in the back seat. Impressively fast and nimble for any car, let alone a heavy one, I found it could comfortably double recommended highway exit ramp speeds w/o noticeable oversteer or tire complaint. The silent V8 had real thrust to adjust high-speed handling and accelerate from 100+ mph. As the owner of an 01 M Coupe, I tend to like odd-duck styling. My impression? This car is fun and off beat. (And probably superior to the E-class my father owns - he thinks so.) I was guessing this was what a Tokyo gangster must drive.

  Look no further - 2004 Infiniti M45
  By Tbone - November 4 - 3:43 am

  I havent loved a car this much since my 88 Mustang Conv. GT. The 2004 M45 is fast, comfortable, anf hot with all the jazz. I stopped talking to the car after two weeks (voice activated stuff is cool but useless once you know what to push). In a car with this much electronics and intelligence, the analog clock is a wonderful touch. The interior is gorgeous.

  So Smooth! - 2004 Infiniti M45
  By m45 owner - January 28 - 10:00 am

  Giant engine thrust and silent cabin, clean understated lines, comfortable appointments and no defects in 5,ooo miles, better than 01 M Coupe, 02 Benz E previously owned. Narrow width and cabin isolation make it good city car, power and wheelbase a fine highway cruiser. At cruise cont. 60mph got 28mpg. Very pleased. Super low price.

  M45 vs 540i - 2004 Infiniti M45
  By bunny1 - March 24 - 10:00 am

  Just traded a BMW 540i for the M45. Beemer went into the shop one time too many. Slightly less than 540i in pure kick ass performance but a whole ton of very nice amenities that cost $1,000s more from BMW. Closest car I could find in overall performance to replace my 540i and reduce the maintence costs substantially.

  Best of Class - 2004 Infiniti M45
  By theyoke - November 27 - 12:40 am

  I was passing a used car lot and saw this car, it looked interesting. The interior looked refined, comfortable and luxurious. Then I took a test drive and was hooked. Actually, test drove 3 of them and a Q within a month. This is a hard car to find and worth the effort to look. I got a black one with spoiler and the premium pkg last week. I drove it on a winding back road on Sunday. It was fantastic. The handling is exceptional on winding roads and freeways alike. The acceleration is unbelievabe and the amenities are the best in this class. The voice command system is great along with the sound system. Its a great car that you rarely see. Test drive it and youll be hooked too!

  A very well built driving machine! - 2004 Infiniti M45
  By Doublewoods - May 27 - 8:16 am

  I have been driving Infiniti M45 since Sept. of 2004. It has lots of power with smooth acceleration and great braking system. Internal design is very well done with almost all of the fancy features you can think of.

  A consistant 21 mpg with 80 percent highway and 20 percent city. Outstanding performance and handling for the 2 lane roads.

  Wolf in Sheeps Clothing - 2004 Infiniti M45
  By nbeyond - March 5 - 5:36 am

  Went in to look at the G35, but was not as impressed with that car as reviews had led me to believe. Actually hadnt heard of the M45, but was immediately attracted to the interior design and comfort before I drove it. Then, wow! Clearly, a refined muscle car. You just dont expect to get quick acceleration and tight handling from what is essentially a luxury sedan. The Edmunds review compares the looks to a Cadillac DeVille, but with the rear spoiler and after adding custom chrome wheels, they couldnt be more wrong. I drove the Cadillac STS-V and BMW 545 before picking this car--couldnt see a good enough reason to spend another $10-15K. And, gotta love the reliability reports!

  hot car - 2004 Infiniti M45
  By fariaro - January 21 - 10:00 am

  My only complaint is the transmission. It is rough and at certain rates of acceleration appears to not have enough torque for that gear, then downshifts.
