  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.

  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.

  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.
