2006 Infiniti M45 Sport 4dr Sedan (4.5L 8cyl 5A)


Review

This is an amazing sports sedan sleeper. The various car magazine comparisons all rated the Infiniti M45 top of the class in 2006 and 2007. I found this car listed on a Jalopnik review for top used luxury car bargains and boy were they on top of it. The 4.5 V-8 is incredibly smooth and powerful. The best feature of all is that the car drives and handles amazingly! In addition, basic maintenance items like brakes, wheel bearing hubs and other little issues on a 9 year old car are super easy to fix and parts are very affordable. Many parts have an identical low-priced Nissan part number if you do a little research or lurking around on nicoclub.com I also drive this car year-round and with Michelin X-ice tires it is remarkably sure-footed in the snow and ice. If you've been driving around in a Camry or Accord or Fusion or other plain old 4 door sedan, do yourself a favor and consider what I did. I sold my 2013 Accord through Craigslist and picked up the 2006 Infiniti M45 Sport and had $5,000 left in my pocket. I went from plain old transportation to one of the best used sports sedans this side of a BMW M5 but without the reliability concerns!

2006 Infiniti M45 Sport 4dr Sedan (4.5L 8cyl 5A)


Review

Wanted to give a long term persepctive on the M45 (Sport) I have put over trouble free 60k miles on the car. I must say it has surpassed the high expectations I had when I bought it 5 years ago. I had purchased the car after Car & Driver rating it higher than the 5 series. I drove several of the competitors and was sold due to the handling, power, technology, build quality (only Nissan built in Japan in 06) and vale. It price out 15k less than comparable BMW, lexus & Mercedes. The car continues to deliver all the positive traits to this day!


Best Features

Handling/ build quality...still as tight as the day I bought it. Strong and smooth V8 that sounds terrific with an Injen intake! Very comfortable highway cruiser for the whole family, the seats are better than my previous Recaros and the other creature comforts are top notch. The suspension, road noise and handling improved greatly with different tires (Hankook V12's!) Reliable, sophisticated vehicle. Definitely the best car i have ever owned!


Worst Features

Fuel economy was advertised as 16/21 and i have consistently got 20 mpg over the life of the car. I am an aggressive driver that put on mostly highway miles. Adaptive cruise control is way too sensitive and the firmware upgrade needs to be done after every battery disconnect.

2006 Infiniti M45 Sport 4dr Sedan (4.5L 8cyl 5A)


Review

This newer M45 made a big impact on me after trading in my G35 coupe. The front fascia resembles the Infiniti family tree. The overall styling is modern with a touch of upper level class. The car itself looks great but with the optional aero-kit, it really makes a bold statement. The interior is good but could use better front seat with multi adjustment seat of other cars in the same class. It only offers your basic functions. Good take off from a stand still but runs out of steam after 75mph. Transmission shifts good but could use the 2009 7 speed transmission. Good pricing and good high quality building makes structure solid.


Best Features

Style and good lower rpm torque. Easy to use interior controls and very good voice commands. Rear seating is spacious with adults.


Worst Features

Upper rpm hp or torque. After installing a cold air intake and full after market exhaust made a huge improvement by 42hp and 51 lbs of torque by dyno numbers. Front seats could use more adjustments.

2006 Infiniti M45 4dr Sedan (4.5L 8cyl 5A)


Review

06 M45 non-sport journeyman off lease 32k miles. So much fun to drive you just don’t want to get out. Powerful and smooth acceleration at all speeds. All controls are easy to operate. I’m 6’4 & fit very well in terms of head and leg room. The M45 was the right combination of power, ride quality and technology goodies for me. The Bose sound system is wonderful. The M45 sport was just too stiff a ride for me. The M35 does not have the same power, only 1 MPG difference anyway. I bought the Infiniti extended warranty (bumper to bumper) till 100k miles or 2014. Infinity also has the best car loaner program. You always get a loaner (g35) no matter how old or out of warranty your infiniti.


Best Features

Price. Power & ride quality. Extended warranty and loaner program. This is just a cool powerful luxury sports sedan.


Worst Features

More power (did I hear M50 390 horses)?
