Traded in a 09 Maxima for the 08 Infiniti M45X. I test drove the 08 G37 and a 08 BMW 550. The G 37 actually drives better but I figured I would get the top of the line and go with the M. The car does not turn heads but as the other reviewer put it, you get pampered when you get inside. I had a Maxima prior to this so I understand all the gadgets. Everything is laid out well. It has great power, you will not get embarrassed on the acceleration lane and on a smooth road you cant tell the difference between 65 and 85. The surround sound is like a concert hall. Around town the ride is a little bouncy, you will feel most bumps in the road and the M goes through gas.
I leased mine with a two year contract. At the end of the lease, I am very happy with the car. It has good acceleration, its comfortable and its stylish but not over the top. It doesn't attract too much attention but when I sit inside I feel pampered. Good features are ride and technology. Bad features are gas mileage and noise level.
Love the car but I have a clunking noise coming from the rear of the car. Infiniti knows about this & it's been with the M series since 2006. They say its "unfixable". WHAT??? I am very displeased with the way Infiniti is handling this problem and plan to take it to the fullest, if it should come to that.
After thoroughly reviewing several cars from BMW (3 and 5 series), Jaguar (XF), Mercedes (C class), Lexus (IS F), I settled upon the M45 sport, almost fully loaded (lacks mobile DVD system). Some of these cars are like comparing apples to oranges but, the M45 above all others is best in overall value to performance – it has the best of all worlds. It offers great performance, plenty of space, excellent design and the best technology features of anyone. While all the other cars were always sorely lacking in some features (for example, the IS F lacks space, the Jag lags in technology, etc.), the M45 simply glimmers best in everything overall, and at a respectable price comparatively.
