Used 2004 INFINITI M45 Sedan


2004 Highlights

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.

It's going to be a classic
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.
A lot of car for the money!
I wanted a Mercedes E500 since I've been driving Mercedes cars three years, but it stickers for $63k with the options I like. I decided to look at the 2003 Infiniti M45. The performance is fantastic! It looks great inside with plenty of new tech equipment and the exterior design is classic and modern. It has 340 hp compared to 302 hp in the Mercedes E500 and $17000 less on the MSRP. WOW!!! I love this car.
The Best Infiniti I Have Ever Owned
This Infiniti looks beautiful and is a pleasure to drive. The car is well built and safe. Passengers tell me it is comfortable as well. The spacious trunk is great, and the navigation system has helped me out in many instances. I am a proud owner of a M45 Infiniti!
