  I love this car! - 2006 Infiniti M45
  By mbeirwagen - February 22 - 5:26 pm

  I have been driving luxury vehicles since 1995 and I am absolutely blown away with my M45. Once I understood how to run the controls which are a little intimidating, I have been on the ride of my life....Watch out for cops. The interior is finally luxury for an Infiniti. This is my 5th Infiniti and the others ones had a very plastic interior. Not this one! So much better than the GS 430. You really must treat yourself!

  Dont drive the M45! - 2006 Infiniti M45
  By Vulcan - January 3 - 10:06 am

  I purchased my M45 sport with tech and journey packages 3 weeks ago and all I can say is WOW! This is far and away the best all around car I have ever driven in this class. I test drove BMW 5 series, Audi A6, and Lexus GS430 before I purchased the M and in my opinion the M blows them away. The rear active steering (RAS) makes a subtle but noticeable difference in turning and cornering. The intelligent cruise control absolutely spoils you for long commutes! Why not drive the M45? Well, if you drive the M35 first (6 cyl,280 HP) , youll love it. But if you then drive the M45 (8 cyl 335 HP) youll never go back and it will cost you $7,000 more!

  First car I ever loved... - 2006 Infiniti M45
  By sdcal - January 1 - 11:13 pm

  I have almost 3000 miles on my M45 Sport and have enjoyed every single one of them. Even those when I was stuck in S CA traffic. The car is very fast, very fun, and very comfortable. I do not understand those that compare the car to a maxima or G series Infiniti. Theres no comparison.

  fantastic car - 2006 Infiniti M45

  This car is really fun to drive; terrific acceleration on the freeway. As a former Lexus owner, the road feel of the M45 is a welcome change from riding in a cocoon. The dash console is attractive but a little confusing. Sirius satellite radio is a big plus.

  Love it - 2006 Infiniti M45
  By Kent - December 11 - 8:00 am

  I originally was going to buy the GS 350, but after driving it several times, I felt cramped and I couldn’t even sit in the back seat with out slouching over. Once I drove the M45, it has plenty of room and power (more than the GS430) and costs less. Its a very civilized hot rod! Love it!

  Awesome Ride - 2006 Infiniti M45
  By Burn-It - July 16 - 5:06 pm

  I love it when BMW 5 series owners start messing with me - after I toy with them a little while, they are just a spec in my rearview mirror before they knew what hit them. The M45 Sport Tech is awesome, has incredible torque through all ranges. I compared this against the Lexus GS430, AudiA6, MercedesS430 & BMW545. The M45 Sport has all of the strongest features of each of those 4 wrapped into 1 incredible luxury rocket ship! Very roomy interior and trunk. Although Lexus has a few more electronic gadgets, I like the M45 navigation and heads-up controls better. The interior rocks, not a bunch of plastic like Lexus and not cold like the German makes. No wonder all the mags rated M the best.

  Quiet, Sleek, Rocketship! - 2006 Infiniti M45
  By Walter M. - May 29 - 10:36 pm

  I purchased the 06 Sport M45 w/the Journey/Tech packages.WOW! Ive always owned German made cars, (My last 2 cars were an Audi A6 with bi-turbo,and a 5 series BMW) and this car BLOWS them away! Everything is in a sensible place and easy to reach.The engine is quiet and powerful.The handling on corners is very impressive.The rear wheel of the M45 turns about 1 degree in the opposite direction of your turn. It may not sound like much, but youll be able to see and feel how it handles through turns. The GPS is much better than the one in my wifes BMW X5.Now for the downside, the lane departure system can be a pain in the neck if you love driving on winding roads.The M45 uses gas like its free

  Pleased with my M45 with Premium Package - 2006 Infiniti M45
  By sambar6 - April 21 - 1:40 am

  This car absolutely rocks. The V-8 has "push you back n your seat" torque throughout the power band. The transmission is smooth is regular driving and responsive in spirited driving. Considered Acura RL, Caddy STS and Audi A6. This car blew them all away.

  Fun car to drive, AC seats are awesome, my wife says everyone stares at the car when she takes it out but its really her. I have the sport package and it is great, I also have a 1 yr old and do not suggest the car as a alternative to the minivan

  Best all-around performance sedan - 2006 Infiniti M45
  By calsteamer - January 22 - 9:00 am

  I have spent the past 6 months trying to decide on new car. I tested all comparable cars (BMW 545, Lexus GS430, Mercedes E500, Cadillac STS), and this was by far the best car for the money. Finnaly, a car with Japanese reliability that drives like a german car.
