I purchased this car 1 year ago fully loaded with 65k miles on the clock. The car gets loads of attention and compliments, my mechanic always compliments the powerful v8 and many get surprised when they find out the car has 340 horses under the hood. Ive had a few issues with the car, like the fuel gauge inaccuracy which has left me stranded a few times on the road. My camshaft position sensor failed me at around 75k miles. My only complaint is parts are scarce and everything must be special ordered from infiniti. Other than parts issues, recalls, and general maintenance this car is flawless.<br><br><br><br>

M45: Great Machine

This is a great automobile! The body style is unique and sharp. Although similar lines to the new Cadillac, I find the M45 lines much more refined compared to the "boxy" look of the Cadillac. The interior is very handsome looking. The automatic retracting seat and lifting steering wheel for ease of entrance and exit is a nice touch. The tiptronic 5 speed transmission lets me enjoy additional acceleration and control when I want to have extra "fun". The audio controls on the steering wheel make audio operation safe and easy while in motion. The voice controlled audio and climate control system also make for ease and safety of control while driving.

This car intrigues you. A true Jekyll and Hyde. Lots of power - Manual mode on transmission is worthless. Comfortable seats - Hard to reach seat controls. Nice wood and leather interior - console and glove box are loose. Lots of goodies - Too many steps involved to enjoy them. Feels great up to 120 mph - feels unsafe at 125 mph. Big car - Interior feels narrow. I like the handling and performance of my car, but it does not have give you feedback like my BMW 540i. This car is a sleeper. You can pull away from nearly every car on the road. Stereo system is very nice. Ours is black with tinted windows and chrome wheels - I think the best color for this car. Engine burns lots of oil!

I've had my M45 for a week now. It is by far the fastest sedan I have driven. It will smoke a 540, E430/E500, GS430, A6 4.2 for $10K to $15K less. The look is menacing, especially in Black. The 18" wheels with the low profile tires look HUGE. The interior is first rate and very quiet.
