Overview & Reviews

Following last year's redesign, the Infiniti M45 gets only minor tweaks for 2007. A 10-way power-adjustable passenger seat has been added to the standard features list, along with a compass and a HomeLink remote transmitter. The car's Technology and Journey packages have been revised, and a new Advanced Package has been added. New SAE engine rating procedures have also resulted in lower power figures for the V8, but actual performance is unaffected.

• Explosive power from a smooth V8, roomy cabin, sharp steering, responsive handling, long list of luxury features.

• Some mediocre interior trim, center stack controls can be a challenge to decipher.

  Outstanding to Own!! - 2007 Infiniti M45
  By Wendell - December 19 - 1:40 pm

  Leased this car about 3 weeks ago. Have been following this model since the redesign in 2006. When my 2003 Volvo S80 lease was about to end, I saw an special on the website. I went in to the local dealer and they were able to set me up. although I went in to get an M35, I ended up deciding on the M45 Sport. The 8 cylinder is only 1 mile per gallon different in the MPG. The power of the 4.5L is quiet but very muscular. The interior comforts are great and the overall appearance of the car bring many compliments. Got a 21 month lease on the car at about $100.00 per month more than I was paying for my S80. love driving this machine....

  I forgot to add that I love the 14 speaker Bose system in this car! 5.1 surround sound is just unheard of in a vehicle until now! Wonderful! The 6-in-dash CD changer and DVD in the center console is great as well! This car is like a mobile home audio entertainment system almost. The heated and cooled front seats are great too!

  Luxury at a Lower Cost - 2007 Infiniti M45
  By MMM45 - June 15 - 9:20 am

  I opted out from buying the Sport model due to it being for my wife and the harsher ride. I purchased a used 2007 M45 with 18K. It has the Tech pkg & the Advanced Tech pkg. It may have the 18" wheels, but they are chrome and this car has the ground effect pkg including the spoiler like the Sport model. You cant beat the Graphite Metallic exterior and the black interior color combo! It handles great and has lots of power, though for a V8, I think there is a lot of it capped somewhere in the programming. This car is loaded with features! It has everything except the power rear seat controls. The steering, braking, balance, and power combo is superb!

  Car is fast ! Handles extremly well in sweeping curves exiting off the highways, no one can keep up least of all those tail-gating SUVs, LOL ! Downshifts are awesomely quiet.

  M45 Sport - 2007 Infiniti M45
  By desertfox - August 24 - 11:56 pm

  Purchased this car used w/27,000 miles on it. CPO Infiniti. Im a Lexus guy and still own one but this car really opened my eyes. The ride quality is great, no issues with sport suspension. Interior is quiet as any luxury car I have ever driven. This car takes no backseat to any German luxo sedan out there.

  Great car - 2007 Infiniti M45
  By andy - July 21 - 3:16 am

  Ive driven BMWs 12 out of the last 20 years. Went to look and prices were out of site. Drove 530, E350/550, GS 450h, Audi A6 then the M45. Drove out loaded advanced tech package, spoiler and rosewood. Car is a dream. Has every luxury item that the Germans nickle and dime you with. Very smooth but powerful acceleration. Quiet comfy interior, great stereo and nav, ac seats are great in florida.

  Our 4th Infiniti - 2007 Infiniti M45

  We had a 2003 M45, we thought that car was nice. The 2007 is night and day. Beats the 550 in every way

  m45 - 2007 Infiniti M45
  By rmelli - January 18 - 1:40 am

  I have the M35X not the 45. I find the 6 to be big enough to get me out of any tight spots without any requirement for a larger engine. The car is a wonderful machine. I had to get used to the dash system, but once mastered it became very easy to navigate. I look forward to driving this car as it handles like a dream in the curves an open road. I have owned two Lexus a 2001E and 2000G. Both were wonderful cars but I like my Infinity best of the three.

  Best Car in Class - 2007 Infiniti M45
  By Mak - December 3 - 1:33 am

  I bought the M45 sport 2 months ago and cant be happier with the choice I made. This car handles and drives better than the competing 5 series models I drove and leaves most luxury sedans in the dust. It wasnt the value that drove me to buy this car (it is way cheaper than the beamer) but the overall package. Even the much more expensive BMW 550 doesnt deliver the luxury this car delivers, and I prefer the interior of this car. The back seat passengers have more leg-room and can actually adjust their seats. This is the first time my two kids have stopped fighting over the front seat. The younger one actually prefers the back. Overall, couldt be happier. Love, love the car.
