Review of the 2004 Infiniti M45

  • A capable Japanese sedan that makes a worthwhile alternative to Germany's midsize stalwarts.

  • Safety
  • Pros

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

  • Cons

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

  • What's New for 2004

    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.

Vehicle: 2004 Infiniti M45 4dr Sedan (4.5L 8cyl 5A)

Bought my 2004 brand new right after my BMW 540i came out of the shop, Again. It is an awesome car that is not well known. I took a BMW 530 to task with no problem. No one knows what this "sleeper" can do. Most don't even know what the M45 is. At 70 MPH this car is asking you to please let it go faster. At 100 MPH its asking to please open it up all the way. During that time it feels and handles like a German car and the stereo is going, so pay attention to your driving. If you can't handle or appreciate very fast cars, go get a something else. This one is a dark horse among many wannabes. At today's prices its a steal. They won't be so low for long.

I purchased this car because it had a great review. After the initial purchase my experience was wow! I would love to purchase a new car but I am so satisfied with the overall experience that it make me scared that purchasing another car I will get less. Most new cars are great looking but their performance and overall quality is not as good as the '04 M45. A Mercedes S650 AMG. Talk about money. I guess its the '04 M45 for now and I love. See you on the highway in my rearview. LOL




Best of class

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. It's a great car that you rarely see. Test drive it and you'll be hooked too!




Smooth, fast and love it

Super powerful, handles smoothly, very comfortable. We call it the rocket for the super quick smooth acceleration. It is so great on the highway and around town. Has been very reliable.

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.
