Edmunds' Expert Review
by the Edmunds Experts
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
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.
Edmunds says
A capable Japanese sedan that makes a worthwhile alternative to Germany's midsize stalwarts.

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.
AWESOME BABY

2004 INFINITI M45 4dr Sedan (4.5L 8cyl 5A)
I have had three Q45's before the M45
and this was not a step down. The M45
is a truely enjoyable and fun ride. The
M45 handles the road and is much more
sporty than the flagship Q. The
acceleration is mesmerizing. The driver
seat encompass the body like a glove. A
splendid vehicle. The only negative is
the confusing instumentation.
A lot of car for the money!

2004 INFINITI M45 4dr Sedan (4.5L 8cyl 5A)
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.
So Smooth!

2004 INFINITI M45 4dr Sedan (4.5L 8cyl 5A)
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.
